  • Page 18: Choose Measurement Point

    Choose Measurement Point The Thermal Energy/BTU Flow Meter is simple and convenient to install. As long as a suitable measuring point is selected, Clamp the product sensor surface on the pipe section directly and fix the pipe clamp, and then the power is turned on, the flow measurement can be ealized. When selecting measuring points, it is required to select pipe sections with uniform fluid flow field distribution to ensure measurement accuracy.

  • Page 19: Communication Protocol

    Communication protocol The hot (cold) meter adopts the reply communication method, and th host computer sends “ command”, requires sub-hot (cold) scale responses. The baud rate of asynchronous communication ( Primary station, computer system, hot (cold) meter is generally 9600bps. A single byte data format (10bits): one start bit, one stop bit and eight data bits.

  • Page 21: Modbus Protocol

    MODBUS Protocol This MODBUS Protocol uses RTU transmission made. The Verification Code uses CRC-16-IBM (polynomial is X16+X15+X2+1) shield character is 0xA001) which is gained by the cyclic redundancy algorithm method. MODBUS RTU mode uses hexadecimals to transmit data. 8.2.1 MODBUS Protocol Function Code and Format The flow meter protocol supports the following two-function codes of the MODBUS.
  • Page 22 Please notice the order in which the data is stored in the example above. When C programming language is used to interpret values, Pointers can be used to directly put the required data into the corresponding variable address. Generally, the sequence of storage is low bytes first. For example, in the above example of 1.2345678m/s, the sequence of storage of 3F 9E 06 51 data is 06 51 3F 9E.
