<strong>Flow</strong> Data<br />

In this flow data manual we have endeavoured to make the information<br />

as accurate as possible.<br />

We cannot accept any responsibility should it be found that in any<br />

respect the information is inaccurate or incomplete or becomes so as a<br />

result of further developments or otherwise.<br />

Technical Data<br />

HERZ-Stainless steel orifice plate<br />

PN16<br />

The flow rate can be calculated using the K vs value and a measured<br />

signal.<br />

July 2010<br />

Issue 1<br />

<strong>Flow</strong> Coefficient<br />

K v = Q K vs = Q<br />

√ ∆P<br />

√ ∆Ps<br />

where Kv & Kvs = flow coefficient (m 3 /hr at 1 bar differential)<br />

Q = flow rate (m 3 /hr)<br />

∆P = headloss attributable to orifice plate (bar)<br />

∆Ps = differential press across tappings (signal) (bar)<br />

The pressure loss across the orifice plate can be determined by<br />

multiplying the signal by the pressure loss factor.<br />

The pressure loss is always less than measured signal.<br />

Technical Data<br />

HERZ-Commissioning Valve<br />

PN16<br />

<strong>Herz</strong> 2740 orifice plates can be installed in isolation or close coupled to<br />

a globe double regulating valve complying with BS 7350, of the same<br />

nominal diameter.<br />

July 2010<br />

Issue 1<br />

Installation<br />

Regardless of installation there must always be a minimum of 5 pipe<br />

diameters of straight pipe, without intrusion, upstream of the orifice<br />

plate.<br />

When used in isolation a minimum of 3 pipe diameters of straight pipe<br />

are required downstream of the orifice plate.<br />

When close coupled to a <strong>Herz</strong> 4218 double regulating valve no straight<br />

pipe is required after the valve.<br />

When used in conjunction with a butterfly double regulating valve, a<br />

spool piece equivalent to a minimum of 2 pipe diameters is required<br />

between the orifice plate and butterfly valve.<br />

For more detailed instructions please refer to the Installation, Operation<br />

and Maintenance Instructions supplied with the orifice plate and valve.<br />

Once the required flow rate has been calculated, the size of the orifice<br />

plate can be determined based on the following:<br />

The minimum signal at the design flow rate of 1 kPa.<br />

For minimum pressure loss, a maximum signal of 4.7 kPa, which<br />

corresponds to the maximum differential pressure range of a<br />

fluorocarbon manometer.<br />

Sizing<br />

The pressure loss across the commissioning set is the combined loss<br />

attributable to the orifice plate and double regulating valve.<br />

The double regulating valve shall not be used less than 25% open.<br />
