How to set the transmitter range based on the flow calculation sheet
Thread Content
This is a multivariable transmitter with temperature compensation; I’ve never worked with one of these before, it’s the EJX910A from Yokogawa
The Weilibi flow meter belongs to the differential pressure type of flow meters, and the range of its differential pressure transmitter is the maximum differential pressure value
The rated flow rate is 43,000 standard cubic meters, corresponding to a differential pressure of 824 Pa. Is the manufacturer trying to play hide-and-seek with the user, forcing them to calculate the differential pressure themselves?
Generally, multi-parameter systems require specialized software to be connected to a computer for configuration. I’ve seen before that Yokogawa has its own PADs, which are small industrial tablets used for debugging. Without these prerequisites. Even professional instrument operators cannot operate it. This doesn’t seem to be like an ordinary differential pressure transmitter that only requires setting one scale differential pressure. Multi-parameter transmitters require a lot of configuration. Including physical property parameters, and so on
The upper limit for the differential pressure is 823 PA; that’s it
I’ve never done this before; it’s a multi-variable transmitter for gas, equipped with a temperature-compensated thermistor
