    What to do if there is no flow through Liquid Controls Measuring Instruments?
    • C
      criddleAug 17, 2025
      If your Liquid Controls Measuring Instruments meter is not flowing any product, there might be a few reasons. It could be due to a faulty or non-functioning pump, a valve that is not open or not working correctly, or the meter might be 'frozen' because of chemical 'salts' or foreign material buildup inside the metering chamber. Consider cleaning the meter and inspecting for any damage.

    Why is my Liquid Controls Measuring Instruments meter running too slowly?
    • S
      Scott EspinozaAug 23, 2025
      If your Liquid Controls Measuring Instruments meter runs too slowly, several factors could be the cause. The valve's internal mechanism might be faulty, preventing it from fully opening. Also, the meter gears or rotors could be partially 'salted', which slows down the rotation of parts. Cleaning the meter might help. Another potential cause could be a downstream restriction or a clogged strainer basket.

      If you observe leakage from the cover gasket of your Liquid Controls Measuring Instruments, it might be because the gasket has been damaged due to shock pressure, or the cover bolts haven't been tightened sufficiently. Replace the gasket and ensure the cover bolts are correctly tightened.

      Tara JosephAug 28, 2025
      If you notice leakage past the packing gland drive shaft housing from the internal metering chamber in your Liquid Controls Measuring Instruments, it's likely that the internal seal of the packing gland assembly is worn. Replace the packing gland and O-ring seal.

    What to do if product flows through Liquid Controls M Series but the register doesn't operate?
    • K
      Kari MaddenSep 12, 2025
      If product flows through the Liquid Controls Measuring Instruments meter but the register does not operate, check the packing gland and gear train. A faulty register should be checked and repaired by a trained mechanic. Also, replace the packing gland, as this may be caused by starting the flow too rapidly.
