Key Features and Characteristics:
Utilizes a proprietary liquid booster pump or electric booster unit (developed by Shandong Hengrong) as the pressure source, offering steplessly adjustable output pressure and freely configurable pressure-rise rates;
Equipped with an automatic air-purging and liquid-filling system to rapidly vent air and fill the flow meter under test with liquid;
Test parameters—such as test pressure, holding pressure, and holding duration—are configured via computer software, allowing the testing process to be completed automatically;
Features automatic pressure compensation during testing, ensuring a high level of automation, ease of operation, and reliable performance;
The test bench automatically shuts down and triggers an alarm in the event of a leak or overpressure; an emergency stop button is available for immediate pressure release during critical situations;
All valves, fittings, and connectors are made of stainless steel, ensuring pressure ratings and safety while making the system compatible with a wide range of liquid media.
