The flanged differential pressure transmitter is a differential pressure transmitter which is connected with the flange and the measured object, which is used to measure the parameters of liquid level, boundary surface and proportion. It can continuously measure the flow of liquid, steam and gas, and convert the measured parameter values into uniform standard gas pressure signals.
Single flange insert pressure transmitter parameters.
Measuring object: the liquid level of the opening or sealing vessel.

Communication output: communication distance: 1.2Km (using CEV cable) 1, 4mA ~ 20mA DC output + field bus HART
Protocol communication distance: 2Km (using CEV cable) 2, 4mA ~ 20mA Dc output
Vibration influence: on any axis, the frequency is 200Hz, resulting in the error of the maximum range of 0.05%/V
Power impact: 0.005%/V less than the input range
Load impact: as long as the terminal voltage of the input transmitter is higher than 12V, there is no load effect
Effect of installation position: the minimum error of 0.25kpa can be produced, but it can be corrected, no impact on the range, and can be corrected and eliminated.
