Automatic Test Bench to Calibrate water meter calibration system
Master meter method, volumetric method calibration equipment for caliber(DN15~DN50) water meters and microcomputer automatic control system
Main technical parameters
- Calibrated caliber size: DN15~DN50
- Calibration method: master meter method, volumetic method
- Uncertainty of equipment expansion: master meter method 0.2%,0.5%;volumetric method 0.05%,0.1%
- Structural style:skid-mounted
- This calibration equipment for water flow is applied to various small caliber volumetric method flowmeters or water meters
- 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
- with skid-mounted design, 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 adopte

Temperature and pressure transformer:
Regulating valve:
Pneumatic control valve is to use compressed gas as power source, cylinder as actuator, and with the help of valve positioner, converter, solenoid valve, position retention valve, gas storage tank, gas filter, etc.
Filter and other accessories to drive the valve, realize the switch value or proportional adjustment, and receive the control signal of the industrial automation control system to complete the adjustment of the pipeline medium: flow, pressure, temperature, liquid level and other process parameters.
Pneumatic control valve is characterized by simple control, fast response, and intrinsic safety, without the need for additional explosion-proof measures.
Meter clamping device:
Clamping device;
Run mode: run in pneumatic side
Water pump of standard calibration equipment:
Water tank:
1:The water tank adopts 40*100*3 stainless steel square tube as the skeleton welding semi-closed structure; and uses 3mm sheet metal as the sealing plate;
2:Upper cover plate on water tank;
3:The water tank is customized and made of high-quality thickened stainless steel
Shield:
Equipment:
- There is a stainless steel protective cover with a transparent viewing window at the operating position;
- All pipe sections are supported and fixed by brackets.
Safety system:
1) All AC wiring positions are located in places that are not easily accessible by operators, and all connections are in the form of plugs and sockets, and no external connectors are provided. Under normal use, the operator is not in contact with the alternating current;
2)The metal operating surface contacted by the operator is well grounded;
3)All equipment used in the system is installed in the cabinet and fixed by structure to prevent people from falling and hurting people;
4)During the test, the operation door will be locked to prevent misoperation and harm to the human body;
5)There are perfect emergency stop and fault protection mechanisms in the system. If the emergency stop button is pressed, the system will automatically cut off the control power and air supply. The action process is controlled by a reliable safety relay to ensure fast and reliable response to abnormality.
