Temperature measurement system

flow

In order to provide high precision and accuracy in calorie measurement, the flow measurement method operating on the ultrasonic principle and temperature measurement with the PT100 temperature sensor are used. The main unit calculates calories by estimating the energy difference between the temperature sensors according to the flow rate it receives and the temperature difference between the 2 temperature sensors. Ultrasonic calorie measurement system manages to calculate calories in the following units. ➢ Giga Joule ( GJ ) ➢ Kilocalories ( KC ) ➢ Kwh ➢ BTU The basic parts of the system consist of flow measurement sensors that allow measurement from outside the pipe, produce high-frequency sound and detect the return of this signal, temperature sensors that detect the inlet and outlet temperatures with high sensitivity and transmit them to the main unit, and the main unit that performs all calculations and operations according to the information it receives. The main unit measures the inlet and outlet temperature. It calculates calories by calculating the energy difference between these 2 points with the flow measurement made using this temperature difference. The system transfers this information to Modbus-Profibus converter via RS485Modbus output and calorie information is transferred as Profibus.
