Seeking help regarding the mass flow meters of E+H 80 and 83
Thread Content
Help: When using the mass flow meters of E+H 80 and 83 to measure standard cubic meters, is it necessary to change the density to the standard value?
It’s not necessary~ The term \"standard density\" refers to the density under standard temperature and pressure; if you don’t specify custom temperature and pressure conditions, using the standard density is incorrect. It’s possible to measure the density at 80 or 83 as well, so using the density obtained through normal measurement will actually result in higher accuracy.
So what parameters do I need to change when converting cubic meters to standard cubic feet?
Choose either temperature or pressure to input~~
To display density values on the DCS, using pulse-type wiring – is a pulse transmitter required in order to show them on the DCS?
The E+H 80 can output 4 HART signals, which can be read as long as the DCS card supports HART functionality. The 4 values include: the current value (the 4-20mA value), temperature, density, and one more value that I can’t remember.
