FlowHUB Series Flow, Temperature,Measure, display, switch, transmit Up to l 360 lpm, 100 US gpm l 420 bar, 6,000 psi The FlowHUB is ideal for condition monitoring, test stands and closed loop control applications both for fluid power and lubrication systems. The FlowHUB can measure and display flow and temperature readings as well as switch and transmit flow values. This enables a system designer to trigger alarms, shutoffs and transmit real-time values to a PLC using just one component, instead of up to six which might have been required conventionally. This represents a significant cost saving in terms of reduced complexity of wiring and far fewer components. It is available in five flow ranges from 1 to 360 lpm (0.25 to 100 US gpm) and in two pressure ranges 210 and 420 bar (3,000 and 6,000 psi). The FlowHUB is available in three versions - ‘Switch’, ‘Transmitter’ and ‘Ultimate’, all three versions have built in temperature measurement and a large bright digital display. The ‘Switch’ version provides two configurable switched outputs; the trigger flow rate, time delay, sense (above/below) and normal mode (normally closed / normally open) can all be freely configured. Each switch is independent and can switch up to 500 mA. The ‘Transmitter’ version provides a conditioned output either 0 to 5 Volts or 4 to 20 mA - full scale is configurable to any maximum flow. The ‘Ultimate’ version has both the switches and transmitter and the highest pressure rating of 420 bar (6,000 psi) as well as an enhanced response time of 50 ms.

Filtration It is recommended that a 25-micron filter is installed in the hydraulic circuit prior to the FlowHUB. Reverse flow operation The FlowHUB will allow reverse flow but it will not measure the flow rate. The pressure drop in reverse flow is considerably higher then that for forward flow. Please see chart below for details. Calibration The above specification is met without ‘wet’ calibration - if full traceable calibration is required then please state at the time of ordering - this is an option and will incur an additional charge. As standard it is completed at 21 cSt (ISO 32 oil at...
