Product Description factory price Liquid 4 20mA Industrial Wastewater Digital Electromagnetic Liquid FlowmeterProduct Description1 Wiring1.1 Signal and Exciting Line1.1.1 Signal Line DisposeWhen 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 CableTwo 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. 1.2 Meter Terminal WiringSymbols and Description of Terminals: Table 1.11.3 Output and Power Supply LinesAll lines for signals transferring and power supply should be prepared by users. Take note that the lines should meet Load current requirement.1.3.1 Frequency and Pulse Output Line The figures below show frequency and pulse output connection with power supply and load. Diode should be added when using inductive load. 1.3.4 Ground Line ConnectionThe ground terminal of heat meter shell should use larger than 1.6 mm2 copper ground line. Contact resistance should be less than 1Ω.2. Meter Parameters2.1 Flow Parameters2.1.1 Working ModeXFER Series have three working modes: Heat Meter working mode, Cold Meter working mode and Heat & Cold Meter working mode. Heat Meter working mode: default mode, measure on heat. "H" stands for heat. Cold Meter working mode: measure on cold. "R" stands for cold. Heat & Cold Meter working mode: measure on both heat and cold. Measuring results display separately.2.1.2 Measuring Pipe SizeCold and Heat meter sensor pipe size scope of XFER Series is 10-2000mm.10, 15, 20, 25, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 800, 900, 1000, 1200,1400,1600,1800 and 2000.2.1.3 Flow UnitFlow units included m3/h.2.1.4 Heat Unit and Cold Unit Displayed heat unit includes MJ/h,GJ/h,KWh/h,MWh/h 2.1.5 Measured Damping TimeMeasured damping time means filter time. Long measured damping time can enhance the stability of flow display and output signal and be applied for gross add up of pulse flow. Short measured damping time means quick respond to measurement and be applied in production control. Measured damping time setting is by choosing.2.1.6 Flow Direction ChoosingWhen doing debugging, if the flow direction is not consistent, users don't need to change connection of exciting and signals lines, just to reset the flow direction parameter.2.1.7 Flow Zero-point CorrectionMake sure the senior is full and the fluid is in stationary state when doing the flow zero-point correction. Flow zero-point is shown as velocity of flow, unit is mm/s. Zero-point correction displayed as below:Upper small characters: FS means measured zero-point;Lower large characters: corrected flow zero-point.When FS display is not "0", do correction to make FS display "0". Note: if correct lower line character and FS increases, change the "+, -" in lower line to make sure FS display to be zero.The corrected flow zero-point is the compound value of sensor, and should be recorded in sensor list and label. The unit is mm/s, and the sign is in opposite with corrected value.2.1.8 Small Signal Elimination PointSmall signal elimination point setting is showed by flow. When small signal is eliminate, only the velocity of flow, elimination flow, percent display and signal output are displayed.2.1.9 Temperature Gaps Signal EliminationWhen the temperature gaps of the flow entry temperature and flow outlet temperature is less than the setting temperature, the meter will not calculate.2.1.10 Flow Integrating Unit9 bit calculator is applied and the upper limit is 999999999.Unit is m3 and flow equivalent is 0.001m3, 0.010m3, 0.100m3, 1.000m3.2.1.11 Heat and Cold Integrating Unit9 bit calculator is applied to Heat Meter and the upper limit is 999999999.Heat integrating unit is MJ,GJ,KWh,MWh.Heat Equivalent:0.001MJ, 0.010MJ, 0.100MJ, 1.000MJ0.001GJ, 0.010GJ, 0.100GJ, 1.000GJ0.001 KWh, 0.010 KWh, 0.100 KWh, 1.000 KWh 0.001 MWh, 0.010 MWh, 0.100 MWh, 1.000MWh Note: Cold integrating has direction display and one bit less than heat integrating.2.1.12 Reverse Measurement Forbidden XFER Series Heat Meter and Cold Meter has the function of reverse measurement forbidden. If the function is applied as "Forbidden", no output for heat and cold measurement and only flow velocity is able to display. If the function is applied as "Allowed", all other functions work as intended. As default, if the flow is reverse, heat and cold integrating will not be measured.
