Flow meter issue. ! ! ! !
Thread Content
May I ask, **: What parameters need to be set before operating a V-cone flow meter or a mass flow meter? I have a terrible headache right now. . . Hollywell, E+H models – waiting online. .
Reply to 1# q275849946: The question is too general, so only a general answer can be given ^_^ Simply put, it’s the zero point and the range. As for how to set it up, just check the instructions – it’s very simple.
What was said upstairs is correct; that’s all there is to it. For V-cone flowmeters, it’s important to pay attention to the setting of the differential pressure value as well as the use of the square root function in operations
What’s the trouble with this problem? Just find the manufacturer, that’s it, right?
Generally, when standard calibration is performed on instruments before they leave the factory, the relevant parameters are already set. You just need to install it on the pipeline according to the instructions; if certain parameters do not meet the requirements after installation and operation, adjustments can be made accordingly. :handshake
V-cone flow meter, configured in the same way as common differential pressure transmitters； Mass flow meter: It is necessary to enter parameters such as the flow coefficient (usually indicated on the nameplate). If the manufacturer or the metrology department has already entered these values, simply check them. Next, verify that the installation direction matches the settings, and then enter the meter’s range; for analog signals, enter the corresponding 4-20mA range ； The pulse quantity input corresponds to the flow rate range for that number of pulses.
This should be obtained from the manufacturer – the product installation and usage manual, which contains detailed instructions and precautions

An E+H mass flow meter, with adjustable range, low-flow cut-off, and alarm for open pipes in horizontal installation – that’s enough!
