Baoji XingYuTeng QFM403 intelligent vortex flowmeter
1.1 Signal and Exciting Line
When meter works with sensors and conductivity of measuring flow is larger than 50μS/cm, under this circumstance, PVVPB 2*0.12*280mm2 model cable (metal shielded signal line covered with PVC) can be used as communication cable for flow signals. The length of signal cable should be less than 100m. Signal lines have to be connected to sensors that were assembled by producers. The meter can output equivalent level of exciting shielded signal voltage so that interference on flow measurement signals can reduced by means of decreasing the distributed capacitance of communication cable. When conductivity of measuring flow is less than 50μS/cm or signals are transferred in remote distances, under this circumstance, double-conductor and double-shielded signal line at equivalent level of voltage can be used. For example, special STT3200 cable or BTS model signal cable (triple-shielded) can be used for signal communication.
1.1.2 Exciting Current Cable
Two conductor and insulating rubber- covered cables can be used as exciting current lines. Suggested model is RVVP 2*0.12*250mm2.Length of exciting current line should be equal to the length of signal cable.
When the model STT3200 cables are used for exciting current, exciting current line and signal line can be put together as one line.
