The 131VF flow module accepts 4-20 mA analog signals of

valve differential pressure and valve position to determine the

flow rate.

The partially-open valve Cv is derived from valve position then

used to calculate flow rate with formula shown below:

Where:

Q = flow (gpm)

DP = differential pressure (psi)

SG = specific gravity of fluid (water = 1.0)

Valve Flow Measurement

The Cla-Val 133VF Flow Metering System is an effective

means of obtaining real-time flow data from a Cla-Val

control valve regardless of valve function and without an

external flow device. Now all Cla-Val control valves in a

water distribution system can be economically integrated

into SCADA control or pressure and flow management

strategies.

The 133VF System is completely self-contained and when

factory installed on new Cla-Val automatic control valves

or field installed on existing valves, accurately measures

flow rate and transmits it as a 4 - 20 mA analog signal. It

can be used on virtually all valve sizes from two through

twenty-four inch and is typically used at pressure reduc-

ing, back pressure, flow limiting, and level control valve

stations.

The system features the “heart” of the 133-01 Flow

Metering Control Valve technology and adapts it for sin-

gle-valve flow monitoring-only applications. The 133VF

System major components are an X117D valve position

transmitter, a differential or inlet and outlet pressure

transmitters and a 131VF flow calculating module. All

components are 24 VDC powered and weather protect-

ed to IP-68 submersible rating. The 131VF module, with

standard DIN rail mounting, contains powerful mini-com-

puter technology for calculating valve flow based on

inputs from the sensors and using the appropriate flow

curve for a particular Cla-Val valve. For increased accu-

racy the 131VF module uses third-party certified flow

curves tested for this particular metering application.

Valve differential pressure measurement can be located

either at the valve inlet and outlet bosses or on pipe

adjacent to the valve providing installation versatility in

all applications and operating conditions.

For applications requiring flow measurement and remote set point

control, see 133-01 Metering Valve catalog data sheet.
