China Wholesale Flow Measurement Sensor Quotes Manufacturer - Cooling Heat Totalizer – ANGJI Detail:
Product Overview
XSJRL series cooling heat totalizer is a microprocessor based, complete functions, can measure the flow meter with various flow transmitter, sensor, and two branch platinum thermal resistance (or temperature transmitter) with the completion of liquid cold or heat metering. Due to the careful reliability design, the instrument has good electromagnetic compatibility and reliability. Because of the high precision A / D converter and good temperature stability of the components, and the floating-point operations, has also taken a number of measures to improve the precision of the system, the measurement of heat cooling metering instrument can be used as heat carrier or cold media, especially for trade settlement and measurement and assessment, in building air conditioning system, after the valve switch, the instrument can be used for summer cooling metering, can be used for measuring the heat in winter, and can automatically convert a dual-purpose table.
