To troubleshoot a 'no signal' issue with your Onicon Measuring Instruments, start by verifying that the meter is inserted correctly into the pipe and that the electronics enclosure is parallel with the pipe. Next, check the 24 V supply voltage and ensure correct wiring to the control system, referring to the wiring diagram. Finally, inspect the turbines for any debris.
What to do if analog signal is incorrect on Onicon Measuring Instruments?
If the analog signal on your Onicon Measuring Instruments seems high or low and does not correspond to the frequency output, check for a ground loop or offset voltage. Disconnect the analog signal input to the control system and measure the analog outputs directly from the flow meter. Re-connect the signal input to the control system and measure the analog signals again. Any difference between these readings indicates a potential ground loop or offset voltage.
Why is the reading too high or too low on my Onicon F-1210 Measuring Instruments?
If the reading on your Onicon Measuring Instruments is too high or too low, start by verifying the pipe size. If the pipe size differs from what's on the calibration tag, contact the factory. Also, ensure the meter is correctly inserted into the pipe and that the electronics enclosure is parallel with the pipe. Check the wiring to the control system, confirm that the output signals are consistent, and that the control system is programmed for the correct flow range or scale factor. Lastly, inspect the turbines for any debris.
What to do if there is no signal from Onicon Measuring Instruments?
If your Onicon Measuring Instruments are showing no signal, first ensure that the meter is correctly inserted into the pipe and that the electronics enclosure is parallel with the pipe. Verify that the 24 V supply voltage is present and that the wiring to the control system is correct. Finally, check the turbines for any debris that may be obstructing the signal.
Why doesn't the analog signal correspond to the frequency output in Onicon F-1210?
If the analog signal on your Onicon Measuring Instruments seems high or low and doesn't match the frequency output, it might be due to a ground loop or offset voltage. To check, disconnect the analog signal input to the control system and measure the analog outputs directly from the flow meter. Then, reconnect the signal input to the control system and measure the analog signals again. Any difference between these readings indicates a potential ground loop or offset voltage. For further assistance, please contact ONICON.
How to fix no flow rate indication on the local display module of Onicon Measuring Instruments?
If your control system displays the flow rate, but there's no flow rate indication on the local display module or BTU Meter for your Onicon Measuring Instruments, verify that all wires from the flow meter are connected to the display module or BTU Meter. Specifically, the frequency output wire (green) must be connected for any ONICON Display or BTU Meter to function correctly.
Why is the reading too high on my Onicon F-1210 Measuring Instruments?
If the reading on your Onicon Measuring Instruments is too high, it could be due to several factors. First, ensure there is adequate straight pipe run upstream of the meter. Verify the pipe size and contact the factory if it differs from the calibration tag. Also, check that the meter is inserted correctly into the pipe and that the electronics enclosure is parallel with the pipe. Confirm the wiring to the control system is correct and that output signals agree. Ensure the control system is programmed for the correct flow range or scale factor, and inspect the turbines for debris.
Why no flow rate on Onicon display module, but control system displays it?
If your control system displays the flow rate, but there is no flow rate indication on the local display module or BTU Meter for your Onicon Measuring Instruments, verify that all wires from the flow meter were connected to the display module or BTU meter. Specifically, ensure that the frequency output wire (green) is connected, as it is essential for any ONICON display or BTU meter to function correctly.
