In differential pressure measurement, a restriction in the pipe creates a pressure difference from which the flow is derived – without moving parts.
The orifice plate to ISO 5167-2 from DN 50 is suitable for liquids, gas and steam (≤ ± 0.5 %). The differential pressure flow meter for DN 15 … DN 250 measures 0.4 … 12 500 L/min and outputs 4 … 20 mA or 0 … 10 V. The matching transmitter for the orifice plate is listed under differential pressure sensors.
