RECOMMENDATION: If you are going to purchase one flow meter for testing all your hydraulic components, a reverse flow, inline flow meter would be the best choice.

The flow turbine can be permanently installed or used for diagnostics. The oil flow through the unit rotates the internal axial turbine. The frequencies generated are processed by digital electronics (a signal converter). Flow effects causing interference are compensated in this process. In the new, redesigned version, the signal converter is now directly integrated into the flow turbine. This allows even simpler operation and supports permanent coupling of the turbine and signal converter components that are matched to one another.

The new turbine also improves the response times/reaction times (from a previous 400 ms to 50 ms) and increases measurement accuracy. The flow turbine is available in six versions for various flow speeds. A pressure sensor can be connected in parallel to the flow turbine by way of the integrated test point. In addition, the oil temperature can also be measured using the temperature sensor connection.

The flow turbine is used in conjunction with the Serviceman, Service Master Easy, and Service Master Plus.

Why choose a reverse flow, flow meter?
Generally, one-way flow, inline flow meters have an integral check valve assembly that prevents the oil from flowing in reverse. This feature is safe when testing hydraulic pumps, but creates a potential hazard when testing double-acting cylinders and reversible motors.

Due to area difference, when flow is restricted at the rod-end of a double-acting, single-rod cylinder, the forces can cause the pressure to increase to a hazardous level – as much as two times the pressure relief valve setting!

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.

• Inline flow meter with reverse-flow

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. An analog flow indicator with an integrated load valve and an analog pressure gauge in one compact unit is perfect for testing hydraulic pumps without removing them from service.

The RFIK mechanical hydraulic tester offers the perfect solution for troubleshooting and servicing hydraulic systems on agricultural and other mobile machinery. The kit consists of a direct-acting flow indicator with a built-in thermometer, a loading valve, and a pressure gauge all built into a strong steel case with a removable lid for protection.

The unit is self-contained and requires no electrical power. The dials are clear and easy to read. Installation is extremely simple, and the test kit can be connected to either the pressure or return lines. The loading valve and pressure gauge allow a progressive buildup of system pressure with the user’s safety in mind.

To meet the needs of maintenance professionals who service a wide variety of hydraulic machinery, we took our most popular flow meters in each flow size and combined them to make this extremely versatile flow meter test kit that covers a wide variety of flows – from 1.0 GPM to 100 GPM (3.8 Lpm to 568 Lpm).

Each flow meter is equipped with an adjustable load test cell so you can generate pressure when it is not safe or practical to do while the machine is operating. Each unit is also equipped with a pressure test connector so you can quickly and easily connect the pressure gauge (included in the kit) to any flow meter without using a wrench. This feature allows you to monitor system pressure while flow testing a component.

Also included in the kit is a compact infrared thermometer so you can monitor temperature during a test. You get all the components you need to flow test hydraulic systems and components safely and effectively, in a compact, rugged, dust-proof carry-case.

NOTE: Substitute the 100 GPM (379 Lpm) flow meter for a 150 GPM (568 Lpm) flow meter at no extra charge.
