The 190PDE portable heat meter is supplied with two matched precision temperature probesthat are to be clamped to the flow and return pipes of the heating or cooling system, they can be inserted into pockets if available or coupled to the pipe using heat transfer cement.

The unit measures the flow rate and the temperature difference, then using the internally stored specific heat capacity and density of the selected fluid at the measured temperature automatically calculates the energy flow rate and energy total. Very accurate measurements are possible easily meeting the accuracy requirements of EN1434. For permanent applications, a 190F unit is available with a BTU computer for heat metering applications.
