Introduction
Flow Indicators are designed for continuous monitoring or intermittent use commissioning and servicing hydraulic systems up to 420 bar
(6000 psi). The large clear 63 mm (2.5”) diameter dial ensures that quick checks can be made to determine pump performance and setting
of ow control valves. They can be used on mobile and industrial hydraulic circuits, also lubrication and coolant systems using oil. These
direct acting ow indicators can be installed in hazardous areas or on applications where no power is available. The ow indicator design
ensures good reliability and minimises the effects of contamination.
The FI range of products is divided into two families:
1. FI750
2. FI1500
This manual covers the FI750 range of products.
Before rst operating the equipment read the whole of these instructions. Safety may be impaired if they are not followed.
Webtec have been designing and manufacturing ow meters and hydraulics components for over 50 years. We operate within a Quality
Management System that complies with the requirements of BS EN ISO 9001:2000 which is externally audited and certicated 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 customers who may have special requirements not covered by our standard ranges

Basic operation
The ow indicator consists of a sharp edged
orice and tapered metering piston. The piston
movement is directly proportional to the ow
rate and the sharp edge orice minimises the
effects of viscosity. The piston is magnetically
coupled to the rotary pointer assembly which
registers on a clear 63 mm (2.5”) scale
displayed in lpm and USgpm. The FI750 ow
indicators should not be installed in circuits
where the ow is reversed.
See our RFI series for reverse ow capability.

Installation guidance
The unit can be installed in any position, horizontal, vertical or anywhere in between. The unit is designed to panel mount or pipe mount.
When panel mounting ensure that rear and bottom faces of the unit are at least 12 mm (1/2”) from any ferrous material such as an iron panel
or base. The piston contains a magnet that can be affected by close proximity of ferrous material. The front face can be mounted directly to
ferrous panels. Two 9 mm (0.35”) diameter holes are provided for this purpose.
The indicator can be connected into pressure or return lines, however, do not reverse ow; the ow indicator may be damaged and will act
as a non return valve.
Problems are generally few but debris from contaminated oil sometimes adheres to the piston or lodges between the piston and seat. This
jams the piston partially open, causing the ow needle to fail to return to zero. For recalibration or repair please contact the service centre
listed on the rear cover of this manual. Care should be taken to ensure that the ow indicator is installed in a position which is not subjected
to excessive pulsation as this can cause incorrect readings. Connections can be by exible hoses or steel pipes.
For heavy-duty applications, for example installation close to a piston pump, consult the Webtec Products sales ofce.
