Inline flow-meter with integral load cell, safety relief valve, and reverse-flow capability -
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: ONE: You omit to open the load valve after installing the flow meter assembly, and you start the pump, or TWO: You inadvertently close the load valve while testing the pump.
NOTE: This flow meter does not read flow in reverse.
The new HYDRA-CHECK® flow meter 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 flow meter will lock a loaded cylinder (vertical) and create a potential safety hazard - a reverse-flow capable flow meter prevents this.
PREVENTS PRESSURE-INTENSIFICATION - In addition, when a non-reverse flow capable flow meter 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 flow meter prevents this.
