Flow Meter

The SafeGauge Wireless Hydraulic Flow Meter removes technicians from the live work area when troubleshooting and testing hydraulic systems in mobile and fixed plant, such as pumps, valves and motors. 

It allows technicians to remotely adjust the load on a hydraulic system while monitoring the live flow, pressure and temperature readings. 

With the MultiTool Pro providing all the information in an easy-to-use interface with logging and reporting capabilities, testing is completed safer, more efficiently, and with greater transparency. Wirelessly view, control and log hydraulic data for a safer and more efficient testing experience.

What Our Customers Say About Us

The SafeGauge products are a great addition to our tooling inventory. Tooling that removes personnel from the footprint of the machine. It makes the technician's job easier. Dial indicators, again, remove personnel from the footprint of the machine. Eliminates technicians from crush/pinch points.

WesTrac

We now have the SafeGauge Dial Indicator units on-site, and they’re an absolute pleasure to use. We look forward to incorporating this new technology into our existing servicing procedures.

Fortescue

We have mandated SafeGauge Pressure Transducers across our entire site and banned regular pressure gauges entirely. SafeGauge products have made our maintenance procedures significantly safer by entirely removing our techs from exposure to high-risk areas. The implementation has reduced the time it takes to do our regular checks by at least 50%.

WesTrac

Just wanted to say thanks for lending us the latest testing kit for the trial on DT5304. Feedback from the team is that it works well and does what it's meant to do. The transducers have good range. The only request is for some extra transducers in the kit as we have already discussed.

WesTrac

This transducer kit is brilliant! Absolutely better than the other one we have; it was raining the day we completed a transmission test on the 793F. We fitted the transducers and sat in the cab, completed the test quickly and very easily, thanks to the new kit.

WesTrac

This tooling has almost halved our workload during live testing and the lads love it as it is a lot more user-friendly than the previous tooling we had. Since then, we’ve purchased another kit after the first one we bought. We highly recommend SafeGauge to others for tooling purchases as the tooling is simple, robust, and user-friendly.

Frequently Asked Questions

How does the over pressure safety valve work? 

If the pressure exceeds the max limit, it bypasses the unit to protect it. This is unlike other devices which have burst disks that would require replacement.

What is the maximum load/pressure?

The device is rated up to 415 bar (6000 psi). The Flow Meter can generate 350 bar (5000 psi) of load in the system.

How is the temperature measured? 

Hydraulic fluid temperature is measured with a probe that is submersed in the fluid.

How heavy is the SafeGauge Flow Meter?

17kg (37.48 pounds).
