It is unsafe to test a hydraulic pump using a load cell, when there is no over-pressure protection. An over-pressure condition can be inadvertently caused if:

1. you omit to open the load valve after installing the flowmeter assembly, and you start the pump.

2. you inadvertently close the load valve while testing the pump.

The new HYDRA-CHECK® flowmeter with integral safety relief valve solves this problem. It allows you to test pumps safely and effectively when there is no in-circuit protection. In addition, it is completely reverse-flow capable.

This feature, further enhances safety when testing hydraulic cylinders.

PREVENTS CYLINDER LOCKUP - Without reverse-flow capability, an inline flowmeter will lock a loaded cylinder (vertical) and create a potential safety hazard - a reverse-flow capable flowmeter prevents this.

PREVENTS PRESSURE-INTENSIFICATION - In addition, when a non-reverse flow capable flowmeter is installed on the live-end of a single-rod, double-acting cylinder, it will cause pressure-intensification if the cylinder rod is extended during the test - a reverse-flow capable flowmeter prevents this.
