FMM840 circulating water heating and heat exchange ultrasonic cold heat meter
OVERVIEW
FMM840 fixed split ultrasonic flowmeter is applied to long-term online measurement of various liquids. The main unit and sensor are installed separately. The main unit can be installed in the indoor, instrument cabinet and instrument panel. The sensor is installed on the measuring pipe, and the main unit and sensor are used. Ultrasonic flowmeter cable connection can realize flow measurement. The coupled temperature sensor can realize cold heat measurement, which is suitable for system integration, water supply, energy saving, water supply and drainage, heat and other network monitoring projects. Widely used in heating, heat transfer, chemical, and other industries.
Applicable occasions: Ultrasonic heat meter is a meter that measures the flow rate by ultrasonic method and displays the water released or absorbed by the heat exchange system. It uses the physical quantities measured by the two sensors - the flow of the heat carrier and the temperature of the inlet and outlet, and then the compensation of the density and thermal enthalpy and the integral calculation to obtain the calorific value.
