• Gravimetric Method Water Meter Test Bench, DN15-DN25

  Model: MJ3210-10

  The bench is a fully automatic water meter verification device designed and manufactured according to the relevant provisions of JJG162-2019 Verification Regulation for Drinking Cold Water Meters and JJG1113-2015 Verification Regulation for Water Meter Verification Devices, using advanced electronic information technologies including industrial automation control, LabVIEW graphical software and machine vision. It meets the needs of water meter manufacturers and metrological technical institutions for testing or verifying the tightness, indication error and electromechanical conversion error of DN15-DN25 water meters.

• Gravimetric Method Water Meter Test Bench, DN15-DN50

  Model: MJ3210-10

  The bench is a full-automatic water meter verification device designed and manufactured according to JJG162-2019 Verification Regulation for Drinking Cold Water Meters and JJG1113-2015 Verification Regulation for Water Meter Verification Devices, using industrial automation control, LabVIEW graphical software, machine vision and other cutting-edge electronic information technology. It meets the requirements of water meter manufacturers and metrological technical institutions to test or verify the tightness and indication error of DN15-DN50 water meters.

• Water Meter Piston Test Bench, DN15-DN25

  Model: MJ3220

  The bench is a liquid flow standard device using cylindrical piston as the measuring standard according to JJG162-2019 Verification Regulation for Drinking Cold Water Meters and JJG1113-2015 Verification Regulation for Water Meter Verification Devices. During the verification, the servo motor drives the piston body to move at a constant speed, presses out the water in the piston sleeve at a constant pressure and flow, and finally discharges it through the meter to be checked. The error of the meter to be checked is obtained by comparing the dynamic indication of each meter to be checked and the standard in the same time. The detection process has a short time cost, and the flow size can be arbitrarily set and automatically adjusted within the flow range of the device; High stability of water pressure and flow.

• Water Meter Test Bench, DN15-DN25

  Model: MJ3240-10

  The bench is a fully automatic water meter verification device designed and manufactured according to JJG162-2019 Verification Regulation for Drinking Cold Water Meters and JJG1113-2015 Verification Regulation for Water Meter Verification Devices, using the combination of gravimetric method and piston method. Q3 flow point is verified by mass method; Q2 and Q1 flow points are verified by piston method, which improves flow stability and saves verification time. It meets the requirements of water meter manufacturers and metrological technical institutions to test or verify the tightness and indication error of DN15-DN25 water meters.

• Volumetric Method Water Meter Test Bench

  Model: MJ3220-06

  The bench is a volumetric method water meter testing equipment using multiple working tank combinations as a standard tank according to JJG162-2019 Verification Regulation for Drinking Cold Water Meters and JJG1113-2015 Verification Regulation for Water Meter Verification Devices. To test or verify the leakage and error of DN15-DN50 water meters.

• Liquid Level Meter Test Bench

  Model: MJ4210-01

  The bench is mainly used to verify various types of liquid level meter (such as float type, float ball type, float type, input type, differential pressure type, ultrasonic type, radar type, etc.) used to indicate and control the liquid level in the industrial process measurement and control system. It has the characteristics of simple operation and high detection accuracy.

• Water Meter Durability Test Bench

  Model: MJ3511

  The bench is used for the reliability performance test of water meters with rotor type and other mechanical structures. It can achieve 100000 intermittent flow tests under the flow Q3 and 100 hours continuous flow wear tests under the overload flow Q4. The software can automatically read and record the parameters such as the water pressure at the upstream and downstream of the water meter, the water temperature at the upstream of the water meter, the duration of the four stages of the cycle in the intermittent flow test, the number of cycles (cycles), the total test duration, and the flow through the water meter, etc. DN15-DN25 test pipes: 1-4pcs, 6 meters series connection in each pipe; Flow: 0-8m³/h. DN32-DN50 test pipelines: 1 to 2pcs, 6 meters series connection in each pipe; Flow: 0-80m³/h.
