    Proline t-mass 65 MODBUS RS485 Commissioning Adjustment 6.4.1 Zero point adjustment At zero flow conditions, the output of most thermal mass flow devices has a strong dependency on the process pressure. The effect on the true zero point of the device, by the static line pressure, is dependant on the gas type and the application demands and in many cases the use of the low flow cut-off function is adequate to zero the device output.
