Water Meterswith ElectricalOutput(All Types & Sizes) - Model ECMDescriptionThe constantly growing penetration of automation and computerized data processing into water usage, in agriculture, industry, urbanic watersupply systems and any other field where more is required than just the traditional mechanical register of water meters, creates a high demandfor measuring instruments which are able to provide electrical information about the flow.Arad Water Meters equipped with electrical output devices combine the high reliability of the hermetically sealed, magnetically driven registerwith a wide variety of electric output options.All existing Arad Water Meters with magnetic registers can be easily upgraded to include electrical output.Application Examples1. Remote ReadingIn combination with a remote reading system, or computerized data acquisition system, it is possible to collect and process water usage data inmulti-apartment houses, in places with no access, or wherever it is required to bring all data to one point.2. Flowrate MeasuringWith the appropriate type of electrical output it is possible to obtain on-line information about the flowrate which can be displayed, stored or both.3. Flowrate ControlWith the appropriate type of electrical output and additional electronic control device it is possible to perform various functions like the operationof valves, pumps or alarm signals according to various preset levels of flowrate.4. Bi-directional Flow MeasurementWith the appropriate electrical output and an additional electronic module it is possible to distinguish between flow directions, to measure andrecord flow rates and volumes passed in each direction.5. BatchingFeeding electrical output to a batching controller enables pre-setting and delivering of accurate volumes of water in irrigation systems, industrialprocess etc.Electrical Output TypesTwo types of outputs exist for various functions as follows:1. “VOLUME” output - for functions related only to the measured volume.Transducer: Reed Switch.Designation: EV2. “FLOWRATE” output - for functions related to the rate of change in the flowing volumes.Transducer: Photo DiodeDesignation: EF3. "VOLUME" output of 1/10 of first pointer volume.Transducer: Photo DiodeDesignation: EF-P22

Registers Types1. REED-SWITCH - VOLUME OUTPUTA 3 pointer register with magnet installed on one of them.Output definition: “Volume output”. Output type: EV.The reed switch sensor is installed in hermetically sealed transparent plastic cover that can be mountedon the register in any one of 3 positions facing the pointer with the magnet.3 values of output are thus available in 1:10:100 ratios.REED-SWITCH - VOLUME OUTPUT x 2Output definition: “volume output”. Output type: EV-D.The output device contains 2 reed switches.All the components are sealed within a plastic module.A unique feature of this unit is the immunity from conditions that might create false pulses due to backand forth fluctuations of standing water in pipe line containing air pockets, or where mechanical vibrationsof the pipe exist.2. PHOTO-DIODE – VOLUME OUTPUTA 3 pointer register with a serrated wheel on the first pointer shaft for activating a photo-diode sensor.Output definition: “Volume output”. Output type: EF-P.The serrated wheel has 10 “teeth” creating 10 signals per revolution, each signal represents 1/10 the fullscalevalue at this position in the register.3. PHOTO-DIODE - FLOWRATE OUTPUTA 3 pointer register with a serrated wheel mounted on the central shaft of the register for activating aphoto-diode sensor.Output definition: “Flowrate output”. Output type: EF.The sensor is installed and hermetically sealed within a transparent plastic cover. The high number of“teeth” and the relatively high speed of the central shaft create a rapid stream of signals in frequencyproportional to the rate of flow. Fed into suitable electronic units these signals are translated into flowratevalues that can be expressed in any desirable units.4. DPE - DUAL PURPOSE ELECTRONICElectronic register showing rate of flow and accumulated volume. The register has LCD with 6 digits.The register has interchangeable presentation (every 30 seconds) between the rate of flow and volume.Mounted inside stainless steel vacuumed encapsulated cup with glass lens, hermetically sealed IP 68.Can be installed on any Arad meter and hydrometer.Can be programmed for various units:Flow Rate: GPM, m3/h, liter/secVolume: Gallons, Cubic Feet, Acre Feet, m324

General Remarks Concerning the Various Types of Electrical Outputs1. All the sensors are mounted on the register in a non-invasive mode.2. All types of outputs may be installed on all ARAD water meters.3. All “Volume outputs” sensors of types EV and EV-D may be installed or replaced without disassembling the register.25
