Square Root Transmitter ST20
- Squared Input
- High precision performance
- High accuracy
The Square Root Transmitter ST 20 is square root computer. It is designed to solve the equation Q = C ??P where ?P is the differential pressure across an orifice, and C is a constant relating the orifice plate to engineering units. Because ST 20 does not use the curve segment, biased diode technique, it provides accuracy and resolution limited only by the stability and calibration of the orifice plate and its transmitter. The ST 20 output is a standard process current or voltage signal that is linearly proportional to flow.
