    Why does my Sotera 825 Measuring Instruments meter read high?
    • O
      Omar KennedyAug 18, 2025
      If your Sotera Measuring Instruments meter reads high, it could be due to air in the system or the wrong calibration factor. To resolve this, prime the system and fix any suction leaks at the pump. Alternatively, use a higher calibration factor.

      webbhelenAug 23, 2025
      Inconsistent readings on your Sotera Measuring Instruments meter can stem from air in the system, particulates in the fluid, or a worn/damaged meter chamber. Try priming the system and fixing any suction leaks at the pump. Install a screen in front of the meter. Cleaning or replacing the chamber may also help.

      eoneillAug 26, 2025
      If your Sotera Measuring Instruments meter is leaking fluid at the inlet/outlet port, it could be due to needing thread sealant or a cross-threaded port. Add Teflon pipe tape to the joint. If the port is cross-threaded, replace the body.

    What to do if my Sotera Measuring Instruments meter fluid flows; meter won't count?
    • V
      Victoria SteeleSep 2, 2025
      If fluid flows but your Sotera Measuring Instruments meter won't count, the meter disk might be sticking, or the driver/magnet may be damaged, or the meter has failed. Clean out the meter chamber. If that doesn't work, repair or replace the chamber assembly or the entire meter.

    • R
      Rachel WalkerSep 4, 2025
      If your Sotera Measuring Instruments meter displays 'Err0', it indicates a calibration error or damaged chamber. Recalibrate the meter using a more accurate container. If the error persists, replace the chamber.
