Yamatake STD920 User Manual

Operation Using SFC Yamatake Corporation
6-26 ST3000 Smart Transmitter Series 900 Electronic Differential Pressure/Pressure Transmitter
6-7-3 :Display or Change Output Format
This function works for flow rate measurement.
Flow rate is proportional to the square root of the differential pressure arising at a con-
tracting mechanism. Flow rate is also proportional to the transmitters output differen-
tial pressure. In the Linear format, differential pressure is converted to electrical
signals and output, without further processing. In the Square Root format, the square
root of the differential pressure is calculated in the transmitter, and the result output.
Display or change the currently-selected format by key operation.
When Square Root is selected, set low-flow cutoff value, flow rate mode, and dropout
format. Refer to 6.5.7.
