To Next PageTo Next PageWhy are my Oval ULTRA UF-II Measuring Instruments making unusual noises?
If you notice unusual noise from your Oval Measuring Instruments, it could be due to a few reasons. Air might be entrapped, so decrease the flow rate and eliminate air in the piping assembly. Alternatively, the metered liquid might be vaporizing, so decrease the flow rate and control the fluid's temperature and pressure to prevent vaporization.
What to do if my Oval ULTRA UF-II Measuring Instruments count while valves remain closed?
If your Oval Measuring Instruments are counting even when the valves are closed, it could be due to a few reasons. There might be leaks in the valve and pipeline, so inspect them. Alternatively, air pockets might exist between the valve and flowmeter, causing the rotors to rock due to pulsating pressure; vent the air and provide a check valve and accumulator. Finally, the supply power voltage might be fluctuating, so eliminate the voltage fluctuation.
Why are my Oval Measuring Instruments leaking liquid?
If your Oval Measuring Instruments are leaking liquid, it may be due to an incomplete seal of the pipeline. Inspect the rear cover fitting bolts for tightness or replace the gaskets. It could also be due to an incomplete seal on the rear cover of the meter body. Retighten bolts at pipeline connections and replace the O-ring with a new one.
What causes analog output to be unusual in Oval Measuring Instruments?
If the analog output of your Oval Measuring Instruments is unusual, the load resistance may be too great. Check the load resistance to power supply voltage relationship and keep them within the specified range.
