Introduction
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 level, 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 analogue output either 0 - 5 Volts or 4 - 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.
Before first operating the equipment read the whole of these instructions. Safety may be impaired if they are not followed.
Webtec have been designing and manufacturing flow meters and hydraulics components for over 40 years. We operate
within a Quality Management System that complies with the requirements of BS EN ISO 9001:2000 which is externally
audited and certificated each year. Beyond compliance to the standard, Webtec is committed to continually improving in
everything we do; with particular emphasis on understanding what matters to our customers and suppliers, and designing
our systems and work to meet their needs. We are always keen to hear from customer who may have special requirements
