Automatic gravimetric test bench
■Test type: Automatic and measurable ultrasonic water meter and mechanical water meter.
■Site: Automatic type saves labor, intelligent operation, low site requirements.
■Operation: The automatic type does not require manual recording, and the monitoring data will be analyzed by computer data to obtain the test results.
■Measuring range: The minimum stable flow can be measured by the automatic test bench is 2L.

Our fully and semi-automated test benches test volumetric water meters (DN 25-200 as well as DN 15-50) for maximum pressure and temperature.
The PC software communicates with a special processor unit via a serial RS 232 or LAN connection to drive the test process. A processor located in the distribution box reads sensor data and controls valves, pumps, shunts, pulse waveform standard meters and test meters.
Test benches can be used for:
Mechanical water meter
Electromagnetic flowmeter
Ultrasonic flowmeter
Other flow meters
Test bench components that come into contact with water are made of stainless steel, brass or water-resistant plastic.
The test bench is equipped with a swivel end piece to turn the meter upside down. This helps remove air from the test line. To ensure the validity of the test, it is recommended to vent the air in the system beforehand.
The test bench adopts a modular design. Components include:
Test Bench, Flow Regulation Assembly and Tube/Balance Assembly (must be connected to an external water source)
Test bench with auxiliary pump unit and flow regulator
Complete test bench including main storage tank (only space and power requirements)
System for reading tested meters
Product benefits
