Magnetically controlled level 

indicator, type ITA 

The product line ITA is used wherever fluid level has to be monitored, 

indicated, and controlled in a reliable way, especially with corrosive, 

toxic, and inflammable fluids. 

The ITA level indicators offer a reliable, accident-free, and 

maintainance-free usage, through a simple and break-resistant 

construction at a maximum process pressure of 320 bar and a 

temperature range from -50 through 400 °C. The fluid level is 

indicated directly with a separation of the measurement and indication 

area. The magnetic transfer of the fluid level from the tank to the 

indicator is continuous and vibration-resistant, even in the case of fast 

changing levels. 

It is possible to mount the indication rail in any position on the pipediameter. 

There is no corrosion of the indication system. The ITA 

instruments may be used in open or closed vessels. A definite level 

measurement without any power supply is guaranteed because of a 

continuous rotation of the wafers, even if a power loss in the plant 

occurs. 

Level measurement tasks 

Functioning: 

A float chamber (2) is connected (1A and 1B) to the tank (1), and 

following the law of communicating tubes, the level in the float 

chamber is equal to the level in the tank. The float (3) follows the fluid 

level and transmitts its movements contact-free to the indication rail 

(4) mounted on the outside. The float has a special magnet, which 

rotates the wafers by 180° as it passes them. This gives a clearly 

defined level indication, with the level shown in a continuous red stripe 

strongly contrasted to the white above. At increasing levels the color of 

the wafer changes from white to red and vice versa. 

The indication rail and the wafers are made of macrolon so that there 

will never be a problem of corrosion in humid and aggressive 

atmosphere. Each wafer has a permanent magnet, that is why the 

indicator is shock proof. Moreover, as there is no turbidness because of 

product contamination of the UV-radiation, the readability remains 

unobjectable even after some years. 

All models are available with electronic alarms, that can be mounted at 

any position during the operation of the system, which renders possible 

an optimal definition of the min. and max. data points. The indicator 

can be equipped with a scale for volume or height (depending on the 

customer specifications). 

Level measurement task 

1) Indicating the fluid level 

2) Monitoring the level with alarm contacts 

3) Transferring the level using measurement value sensors (analog 

signal 4 - 20 mA) to electrical display units 

4) Interface level measurement 

- 3 -


Advantages 

Switches / alarm contacts 

No risk of glass breakage as a result of the separation of the 

measurement and indicator areas. The float principle means that 

changes of the density in the medium have very little influence on the 

indication accuracy. 

Magnetic level indicators can be equipped with an arbitrary number of 

switch contacts. In contrast to electric float switches, switch contacts 

may be installed at any position of the stand pipe. Wherever additional 

float chambers are for float switches, magnetically controlled level 

indicators offer a considerable price benefit. 

Electrical level measurement transducers which use the displacement 

principle must be recalibrated each time the fluid density has changed. 

The price of a magnetically controlled level indicator with integral 

electrical measurement transducer is considerably lower than level 

measurement transducers. The reed chain with an R/I measurement 

transducer can be changed without interrupting the operation. The 

measurement chamber is hermetically sealed - there is no contact 

between the fluid chamber and the reedchain. 

Floats 

The construction of the float requires a great amount of technical 

know-leage. The float with its special magnet can rotate freely in the 

float chamber. The Intra construction avoids a guide wire and other 

devices. The float materials are stainless steel, 1.4571, 1.4435 (316L) 

or titanium (PVC, PP, PVDF in case of the plastics level gages). Floats 

without gas-prestressing are used from a minimum density of 0,35 

kg/dm^3. The maximum process pressure for sealed floats is 250 bar; 

at higher pressures the floats must be relieved from pressure (not to be 

used for condensing media). 

The switches / alarm contacts are secured with pipe clips, and can be 

adjusted to any desired height. The connection is using a 3-core cable 

or casing terminals. The changeover contact can be used as opener or 

closer. The switches are also available as explosion-proof version.

Indication rail 

Materials 

The ITA level gauges can be delivered with indication rails made from 

2 different materials. Macrolon indication rails are resistable to 

breakage. The max. per-missible media-temperature is 120°C, with 

20°C ambient temperature and natural convection as test conditions. 

The rails are resistable to UV-radiation and aggressive atmosphere and 

are sealed against dust by two seal-caps. Aluminium indication rails 

can be delivered as a one part rail up to a length of 6m. The sight cover 

material depends on the temperature, up to 150°C the material is 

macrolon and up to 400°C it is glass. The surface of the indication rail 

can be coated with Säkaphen if required, the standardized surface is 

brown-anodized. 

The gauge chamber and the floats are made of stainless steel (1,4571), 

254SMO (1.4529), 1.4435 (316L), titanium, hasteloy, PVC, PP, PVDF, 

and PTFE. Other material on request.

Information for use type ITA-3 and ITA-6 in Cryo-design 

If Armaflex is used for insulation (t=9mm) the material for the indication rail will be aluminium. As 

standard for the level gauge in cryo-design we use a float chamber 60,32mm with a float from 

titanium (50,8x240mm length) down to a liquid density of 0,6kg/dm 3 ). 

For temperatures below 40°C the Armaflex insulation is double ply, the upper layer only up to the 

indication rail. 

240 

(500)

D 

The customer should also insulate the processflanges. 

For vaporizing media (for example ammonia) we 

recom-mend you to use floats with 4 distance 

sleeves. (In this case the floats are smaller than 

standard floats). This construction prevents 

catapulting the float upwards 

(this would cause switch failures) 

if gas evolution appears. 

The distance sleeves (see 

drawing) hold the float in the 

center of the float chamber, so 

the gas can move away wihout 

shaking the float. 

For temperatures down to 20°C 

we are using a float chamber 

60,32mm and a titanium float 

45400mm, for temperatures 

below 20°C we are using a float 

chamber 642mm and a 

titanium float 50,8500mm. 

distance sleeve 

In every case we use flanges DN50 as drain 

connections (weld neck and blind flange with 

groove and tongue). When the diameter of the 

float chamber is 642mm it is necessary to 

modify the weld neck flange. 

On request by the customer we make use of a small 

hole (throttling part) to transmit the liquid level to 

the float chamber. It stabilize the float movement 

(damping).

ITA - magnetically controlled level indicator with analog signal (4-20mA) - and 

digital display 

Electrical level measurement transductors which use the diplacemant principle must be recalibrated each time the 

fluid density is changed. 

The price of a magnetically controlled level indicator with integral electrical measurement transducer is considerably 

lower than level measurement transducers. 

The reed chain with an R/I measurment transducer can be changed without interupting operation. The measurement 

chamber is hermetically sealed - there is no contact between the fluid chamber and the reed chain. 

With the microprocessor-controlled level indicator unit type 420, the level can be displayed direct in any arbitrary 

physical measurement unit. The indicator has a curve calculator with which nonlinear tank contents can be displayed 

direct in cubic meters. 

- 35 -

Niveau-source 

Measuring principle: 

The resistance chain with the reed contacts are build in a pipe made of material 316SS. This so called 

‘Reed Chain’ is mounted on the float chamber with jubilee clips. According to movement of the float, 

the float magnet closes one reed contact which produces a voltage (or resistance) proportional to the 

height of the liquid in the tank. You get an near-analogous output signal, with a resolution of about 10 

mm. 

The resistance chain receives its power supply from the transmitter. The 4-20mA transmitter output 

signal can be given to an indicator or can be used to drive alarm contacts. In the case of an error the 

output signal becomes higher than 22mA. 

Connection: 

As a standard the reed chain is supplied with a transmitter that is installed inside the housing-head, 2- 

wire connection to the transmitter, is only required.

Description 

Magnetostrictive level transmitter for 

mounting to a level gauge type ITA 

M-300/ M-400 series working on the magnetostrictive principle is 

High accurracy level transmitter for affordable price. The float inside 

of the level gauge type ITA containing a magnet moves along 

the magnetostrictive wire. A pulse generated by the electronics travels 

along the wire. When the pulse reaches the float’s maagnetic 

field, a twist develops in the wire. Reflected from the torsion point, 

the pulse creates an acoustic wave that travels back along the wire. 

The 4…20 mA output of the transmitter is proportional to the level.

INTRA-Automation doesn´t limit you with the 

standard designs cataloged here. Our experienced 

engineering staff, with extensive research and 

development capa-bilities, will customize liquid level 

indicators to meet your specific requirements. 

Modifications regarding the variety of mountings, 

exotic materials and float configurations provides 

compatibly for most liquid media, various tank 

temperatures and pressures, as well as liquids with a 

broad range of specific gravities. 

The ITA-T1S Liquid Level Transmitters, vertically 

mounted in the tank and cable-connected (3-wire) to a 

remote receiver, operates on the float principle. 

A float guided on a non-magnetic tube follows the 

level of the liquid surface, thereby actuating the reed 

switches located inside the tube by means of a built-in 

magnet system. The reed switches shunt over parts of 

a resistor string. 

The magnet system operates the reed switches according 

to the position of the float and thus causes the 

ohmic resistance of the resistor string to change as a 

function of liquid level. 

A current 4 to 20 mA is then obtained as an output 

signal together with the INT5333; INT5333ATEX; 

TMT182 signal conditioner. The float travel distance 

can be limited by stops fitted to the guide tube.

Monitoring 

Combined with DigiFlow 520 these transmitters form 

a complete liquid level monitoring system. Used as a 

separate system within a process control system, 

INTRA transmitters can interface with programmable 

controllers and other industrial microprocessors. 

fig.3: DigiFlow 520 

Interface 

measuring 

Very often dissimilar liquids resides in a tank. Most 

tank gauging methods are limited in these cases, and 

only indicate the level of the uppermost surface. But, 

with using INTRA-Automation ITA-T1S level sensing 

elements, you can easily monitor the interface 

between liquids. By adjusting the specific gravity of 

the magnet float, INTRA can adapt the transmitter to 

monitor the interface of a broad range of media. This 

principle applies to oil and water, slurries, acids, bilge 

and other dissimilar liquids. 

In conjunction with DigiFlow 520 tank level, ITA- 

T1S will help assure that only the “correct” liquid is 

taken from a tank, or introduced into a process system.
