KOBOLD 科宝 UV - Plastic Vortex Transmitter 涡街流量计

"Product Features","The UV vortex meter is a low cost transmitter with all-plastic wetted surface. It has no moving parts and is ideal for low viscosity, corrosive and dirty liquids. Typical applications include chemicals, clean liquids, deionized water, sea water and solvents. In addition, the UV can tolerate some suspended matter. The electronic transmitter is extremely compact. It is calibrated at the factory for a specific liquid, but can be recalibrated in the field. Potentiometers are provided to adjust for zero, span and viscosity. The plug-in electronics module can be easily removed from the meter body and can be re-used should the original meter be damaged. The 4 - 20 mA output can be user scaled for any zero and span in the usable range. The meter will accurately measure up to 125% of the maximum flow listed. The signal for this amount of over-ranging would be 24 mA provided the user has sufficient voltage. Power requirements are a function of total loop resistance. With supply voltages in the range of 13 to 30 VDC, the transmitter can drive into resistances of up to 1000 ohms The transmitter output is directly proportional to the rate of flow."
