Hydraulic flow monitoring device
15/07/2019
Webtec, a specialist manufacturer of hydraulic measurement and control products, has unveiled the FlowHUB ViscoCorrect, an innovative and intelligent hydraulic flow monitoring device with integral temperature measurement and a large digital display, now for use in oils, water and water-based fluids.
Martin Cuthbert, Managing Director of Webtec, said: “We have seen more customers asking for a flow monitoring solution that they can take from stock and quickly configure for their specific application. The FlowHUB ViscoCorrect can be set up easily for use on water and biodegradable (water-based) fluids, as well as conventional hydraulic and lubrication oils, all at the touch of a button; it is a truly innovative solution.”Suitable for condition monitoring, test stands and closed-loop control applications in both fluid power and lubrication systems, the FlowHUB ViscoCorrect can measure and display flow and temperature readings, as well as switch and transmit flow values. Having all of this capability as part of a single device provides system designers with several important advantages. Alarms and shut-offs can be triggered and real-time values transmitted to a programmable logic controller (PLC) using just one unit, instead of up to six discrete hydraulic components, which might have been required conventionally. As a result, both cost and wiring requirements can be reduced significantly.
The FlowHUB ViscoCorrect is available in two ranges, 30 ℓ/min and 240 ℓ/min, with suitability for water or hydraulic oil up to a pressure of 420 bar and a fluid temperature of 5°-90°. There are two programmable switched outputs.
The device has been designed for permanent installation, with few wearing parts, ensuring a long operating life. Moreover, the FlowHUB can be mounted in any orientation and, since the unit has built-in flow conditioning, no lengths of straight tube are needed.
Accuracy is better than 95%, while repeatability is better than 99%, providing users with peace of mind. Response time is almost immediate at 50 ms. Compact yet rugged, the FlowHUB offers a protection rating of IP64 and is supplied complete with fitted adaptors (BSP or JIC male). The device allows unmeasured reverse flow if needed.
