The preparation of pre-operationalSensors installed in the metal pipe of grounding diagram1, grounding line (outside interference device larger installation)2, Flowmeter grounding line (with factory)Plastic pipe or pipe insulation lining grounding diagram1, grounding line (outside interference device larger installation)2, Flowmeter grounding line (with factory)3, grounding or earthing ring flangePipeline cathodic protection installed for the grounding diagram1, grounding device line (outside interference larger installation)2, flowmeter grounding line (with the factory);3, grounding or earthing ring flange must be consistent with the flangeconnecting pipe insulation4, bolts (installed with the flange should be mutual insulation)5, connecting wire, copper cross-sectional area of 16mm. So that pipingand cathodic protection isolate between the sensor.Important Note: the whole instrumentation (including sensors and Transmitter) to run a rigorous adjustment andflow calibration in the factory, one by one after passing the testIn Plants. To the end user, So, it can be put into operation without any adjustments. Therefore, the initialoperation of the problems encountered, should be in accordance with the specifications Reference points oneby one inspection, a careful analysis, troubleshooting. Avoid Blindly tamper to make a good set of adjustmentsto the original instrument to confuse or even damage.Instrument can be put into operation the following steps:1) First open upstream and downstream the valve with Sensor, so that sensors measuring tube filled with testmedium;2. ) Power for one minute, Transmitter showed an immediate increase to a certain numerical value, pls wiring iscorrect or not, when the flow direction is wrong,plsCheck the direction of the sensor installation is correct.3) zero Trim , instrument through the media 15 minutes after the first sensor tightly closed valve downstreamside, and then shut down the upstream side of the valve, so that tubeStop the flow of fluid and no leakage, the flow shows zero. Zero if too high or too low, Pls do Zero Trim on theTransmitter.Specific operations see Transmitter Manual p. 27SENSORS PARTS09SENSORS PARTSTMHttp: // www.flowmeter.ccSENSORS |
