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.

  Gary WilsonAug 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.
