The problem is that with High Precision meters, when there is no flow, some of them display a low flow rate of 1–2 t/h, while this issue does not occur with E+H meters. 1. How can this low flow rate be resolved? Has the low signal level been filtered out at the site? It’s still zero-point calibration; is the mass measurement still accurate after this calibration? This L flow meter is used for trade settlement. 2. Do terminals 3, 4, and 5’s DO refer to discrete signals, while FO refers to frequency signals? What signal does 5 6 NC refer to? 4. What model transmitter does this flow meter use, and does it support MODBUS?
Teacher, does 5 6 NC refer to the RS485 wiring terminals?
