Regarding the measurement with the Rosemount 8732E electromagnetic flowmeter
Thread Content
Hello everyone. Regarding the issue of measuring the conductivity of media with the Rosemount 8732E electromagnetic flowmeter! What is the lowest conductivity for measuring hot water? The medium is hot water at a temperature of around 90 degrees. The four meters continuously display an empty pipe alarm; grounding is normal, and water discharge is normal, but the flow rate is not displayed…
Different manufacturers have different requirements regarding conductivity; although most manufacturers state that a conductivity level of >5 uS/CM is required, values below around 20 result in significant fluctuations and poor accuracy. So the recommendation is above 20uS/CM
Well, I think the same – I tested it last night; the water temperature dropped to 50-60 degrees, and the conductivity was only 7 us/cm. As the temperature rose, the conductivity decreased further. With one water source, four air handling units gave alarms… seems like there’s an issue upstairs**:lol
8732 is really not useful. . . . . . The malfunction of that touch panel is a common and serious problem. . .
If the conductivity is below 20 US, the performance will definitely be poor; it’s better to choose other types of turbines
