The PT878 Clamp On Flow Meter

The Panametrics PT878 ultrasonic flow meter is a clamp-on portable flow meter which can be used to measure most liquids including clean liquids and also some liquids with solids or gas bubbles. The PT878 is suitable for use on all metals and most plastics, on a pipe range from 12.7mm to 7.6m (0.5 inch to 300 inch) without the need to cut into the pipe.

The PT878 clamp-on flow meter is ideal for rental purposes as it is easily installed, up and running in minutes and can be quickly relocated to other pipes.

The PT878 is ideal for many types of survey including:

  • Energy - When combined with PT100's the PT878 becomes a full energy meter ideal for measuring cooling and heating systems. Typically measuring energy used and lost in a variety of applications e.g. testing boiler efficiency on hot water systems, cooling system effectiveness and condensate recovery.
  • Water usage - The PT878 can be used to monitor not only water consumption but also basic leak detection. Another typical application is verifying flow rates of flow meters of different technologies e.g. e/mag, vortex and mechanical.
  • Chemical dosing - For measuring the dosage of chemicals, The PT878 flow meter is ideally suited. Whether highly acidic or alkaline due to the fact the meter is on the outside of the pipe and does not come into contact with the media, chemical compatibility or temperature is not an issue.
