Flowmeters consist of a full flow filter, an electronic Walbro "on demand" fuel
pump, a positive displacement flow sensor and a finned recirculation tank. The
level in the recirculation tank is kept constant with the aid of float feed
valve(s). The engine fuel supply and return are connected to the above tank.
Only the "make up" fuel fed through the valve(s) is measured. The sensor
electrical pulses are either 1ml or 5ml. A cab counter or another type of
monitor indicates the amount of fuel used during the test period required. Each
unit is individually tested and issued with a calibration certificate.

Fuel Flowmeter Systems
A full range of equipment is being
offered to measure accurately the fuel consumption of cars, vans, trucks,
coaches, buses, off-highway vehicles, boats, diesel suburban trains and
test-bed engines from 20kW to 1200kW.
Advanced design and specifications
offer the following advantages:
No drop in performance. The
diesel and gasoline injection flowmeter systems produce no pressure drop in the
fuel supply to engine and no back pressure in the fuel return. Built-in fuel
cooling arrangements assure 'normal' engine behaviour. Engine performance
figures obtained with and without meter are identical.
accuracy. Overall measuring accuracy is better than 1% of reading
throughout the working range (usually 1-100).
diesel systems are suitable for all types of engines whatever their fuelling
No bits and pieces. The flowmeter systems are
integral and contain all the required components in one unit. There is no
separate filter, de-aerator, fuel cooler, fuel pressure relief valve, flow
sensor, fuel pump etc. It means minimum fitting time and an easy change over
from installation to installation.
Good resolution and full
instrumentation. The results are presented in 1ml and 5ml increments
depending on the capacity of the system. Apart from total fuel consumed, the
electronic monitor also indicates time and a trip fuel used facility that can

Engine Test Bed Total Supply Flow
FMS MK 11A. Consists of a full flow filter -
mechanical flow meter with a built in readout display - a finely adjustable
pressure regulator and pressure gauge (0-10 p.s.i.). Assembly is mounted on an
aluminium casting back plate.
FMS MK 11B. Consists of full flow
filter - a mechanical flow meter with built in readout display. Assembly is
mounted on an aluminium casting back plate.
FMS MK 9. Eight versions are available with
various flow sensors and finned recirculation tanks. A fuel pump or gravity
feed drives the flow meter and feeds the tank mounted float-valve assemblies.
The complete system is fitted in a rectangular stainless steel case, 650mm
high. Depending on the model, the width and depth vary from 230mm to 310mm.
Electric fan(s) assure adequate tank and case cooling. There is an equivalent
system to every vehicle-mounted arrangement, including some extra fuel-to-fuel
cooling and / or gasoline injection submerged H.P. fuel pumps. The unit can be
fitted with an electronic Paar Scientific density meter.
LPG Measuring Equipment is Available
and Gasoline Calibrations
All our flow meters are calibrated to the
flow steps issued by the ISO proposal - ISO/DIS 11081.
Each set of
equipment is supplied with a full calibration certificate.
vehicle fuel flow meters can also be calibrated: Flow rates 0.4 - 125 litres
All fuel measurement equipment is available in either 12 or
24 v DC.
