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 flowmeter 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.

  • Whlist the standard applications are:
