  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 M-15 meter running too slowly?

  pgibsonAug 22, 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.
