  • To calibrate the flow rate of chemical metering pumps and chemical injection systems

  • To periodically monitor the performance and accuracy of a chemical injection system

  • To insert accurate dosages of chemical into batch processes


  • Dual Scale:

    1. Total gauge volume in millimeters

    2. Gallons per Hour or Liters per Hour scale for a one minute test of calibration to determine flow rate

  • Mylar laminated scales are protected from attack by harsh chemicals

  • Available in capacities ranging from 60 ML up to 10,000 ML

  • Models with threaded NPT connections on both ends or models with removable slip-on top caps available

  • Rugged construction using transparent PVC pipe and industrial grade PVC fittings

  • Sight tube material is clear and impact resistant superior grade PVC

  • Materials of construction are qualified to handle a wide range of chemicals

  • Lightweight and extremely easy to handle

  • Special sizes available upon request

  • Other materials also available


-T = Threaded NPT Connection Top and Bottom
-S = Threaded NPT Bottom Connection with Removable Slip-on Cap on Top


  • Slip-on cap on "-S" model has a 1/8" diameter vent hole through center

  • Maximum Pump Rates and Rate Scale Divisions in Gallons Per Hour are based on a one minute test

  • Other gauge sizes available. Please contact KENCO to request a quote for options not covered by gauge specifications shown above.
