Flowmeters: 3/8" Beer Meter & Totalising Beer Counter Instruction Sheet
The principle of operation is
very simple. A jet of liquid is
directed at a free running Pelton
wheel turbine in a specially
shaped chamber. The rotation
of the rotor is detected with a
Hall effect sensor. The output
frequency of these pulses is
directly proportional to flow rate
and the total number of pulses
the total volume passed. The
standard bearing material is
sapphire as this gives a long
trouble free life to the meter.
Non-metallic options mean that
these meters may be used with
very aggressive chemicals and
ultra-pure water.

Flowmeters: 3/8" Beer Meter & Totalising Beer Counter: Instruction Sheet
The totalising meter is a stand-alone product that shows the amount of liquid
dispensed since the last re-set. The unit can only be zeroed using a hand
held key fob. The fob can be made to work with single indicators or groups
of devices in a number of locations. The indicator must have power to work
but should the device be disconnected the display will flash when power is
restored and will continue to do so until the unit it re-set using the key fob.
The meter will remember the total at power down and continue incrementing
from that point when the power is restored. The display increments in pints
or litres. Install the meter in a horizontal run of pipe using 3/8” push on John
Guest fittings with the arrow on the back of the meter in the direction of the
beer flow. Connect power to the socket on the side, 7-15 volts ac or dc, a
“plug” type power supply of the correct rating is ideal. Do not use a 24 volt
transformer. We can supply a dedicated PSU for multiple unit installations.
The reset key fob must be held very close to the reset window and the button
pressed for approximately 3 seconds. This close proximity will ensure that
no other meters in the same area are simultaneously reset. The “colon” in
the centre of the display will light up if a reset signal is being received. If a
count in excess of 999.9 is made the decimal point to the right of the hundred
digit will flash. Do not permit the meter to run on gas as this will damage
the device. Where possible fit a mechanical air eliminator (FOB detector).
