Measurement conditions & notes
- Unless otherwise specified, this product is calibrated under the following conditions: nitrogen, 25℃, 2.5 bar differential pressure (inlet 3.5 barA, outlet 1 barA), horizontal position.
- It is recommended to install a straight pipe section of appropriate size at the inlet, otherwise accuracy deviation may occur.
- It is recommended to use the largest possible fittings at the inlet and outlet to avoid additional pressure loss.
- The shown ranges are available for nitrogen.
- %F.S. means error as percentage of full scale.
- %S.P. means error as percentage of setpoint.
- Response time refers to time to reach ±2% of setpoint.
- Working pressure refers to differential pressure between inlet and outlet.
