BTU Meter For Heat Transfer Application

A BTU / Thermal energy meter for flow and total energy consumption

This is a meter for the Heat Transfer application. It measures Thermal Energy carried by various fluids that are used as heat transfer mediums.

Manas heat transfer meter (Model HET-100L) is popular in Thermic Fluid applications. A Thermic fluid heater is industrial heating equipment used for achieving high temperatures at low pressures. A thermic fluid is typically circulated in the entire system for transferring heat to the desired processes. Primarily, the combustion process heats up the thermic fluid. Then the thermic fluid carries and passes this heat to the desired fluid to achieve the required process temperature. After passing on the heat, this thermic fluid comes back again to the thermic fluid heater and this cycle goes on.

BTU Meter For Heat Transfer HET-100L takes care of the compensation of variation in density & specific heat with varying temperatures of the fluid.
It also measures the thermic fluid flow rate & is also useful for measuring thermal transfer for hot water flow.
