•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.
