Flow Meter Test Kits

A flow meter test kit is a crucial tool for measuring the flow rate and pressure of hydraulic oil in hydraulic systems. The volumetric efficiency (internal leakage) of hydraulic pumps will increase with age. Consequently, to prevent unnecessary downtime it is vital to check the efficiency of hydraulic pumps on a routine schedule. The test kit needed to perform the test must be relatively easy to install, safe, and accurate. A flow meter test kit is ideal for testing hydraulic pumps without removing them from service. This portable test kit will give you the same result as testing your pump on a state-of-the-art test bench at a fraction of the cost.

The unit comes equipped with a load cell and pressure gauge which allows the user to load the pump in a safe manner while running tests. The variable area flowmeter on the unit provides a quick, visual flow indication on an easy-to-read linear scale to confirm that flow systems…

HydraCheck adds versatility to its range of inline flow meter test kits by adding a safety relief valve to the load-cell. This unique feature removes the risks typically associated with testing fixed-displacement pumps and single-rod, double-acting cylinders.

For example, in a fixed-displacement pump application, the pressure relief valve is typically located at some distance from the pump, e.g. at the inlet port of the directional control valve. In this case, if the load cell does not contain a safety relief valve, the user is exposed to a hazardous situation.

This problem also applies to testing single-rod, double-acting cylinders. Using a load-cell without a safety relief valve exposes the user to an extremely hazardous situation if the load-cell blocks the discharge flow from the rod-end of the cylinder and causes pressure intensification. HydraCheck’s exclusive integral safety relief valve prevents an overpressure condition when testing hydraulic components by allowing the oil to bypass the load valve at a pre-determined set pressure.
