Calibration equipment for big caliber water meter and microcomputer control system
Introduction: Master meter method, volumetric method calibration equipment for big caliber(DN65～DN600) water meters and microcomputer automatic control system
Main technical parameters:
- Calibrated caliber size: DN65～DN600
- Calibration method: master meter method, volumetic method
- Uncertainty of equipment expansion: master meter method 0.2%,0.5%; volumetric method 0.05%,0.1%,0.5%
- Structural style: tiling
Main technical features:
- This calibration equipment for water flow is applied to various big caliber flowmeters of which medium is water;
- High precision calibration apparatus is adopted for the standard of master meter method, second class metal gauge is adopted for the standard of volumetric method;
- Second class metal gauge can match with first class gauge to transmit quantity, which is more convenient for the calibration of second class metal gauges;
- Microcomputer automatic control system, water pump frequency conversion control are adopted;
