BIF - Model 20612 -Flow Controller

The Universal venturi Tube gives this rate of ?ow controller a high metering accuracy at ±0.5% of actual ?ow rate and gives a very stable ?ow signal to aid in control loop setup and tuning. This excellent performance from the UVT also aids in giving the rate controller a high repeatability ±3% over a 4:1 ?ow rate range. For accuracy and repeatability your rate control system needs a BIF Model 20612 Rate of Flow Controller.

The Model 20612 is designed to ?t the same laying length as the model 20610 Rate of Flow Controller also incorporates a removable, replaceable butter?y valve allowing the customer to standardize on any valve model type and design plant wide.

The Model 20612 Rate of Flow Controller is also sized for optimum controllability. This means typically that the valve is one line size smaller than the nominal inlet of the rate controller. This valve optimization puts the control in the linear control range of the butter?y valve and thus aids in quieting the control loop causing less “hunting” for the proper control point.

Combining the high accuracy UVT with a well-designed and properly sized butter?y control valve in a short ?ange to ?ange length yields a long service life, high accuracy and high repeatability for your rate control needs.
