The LPC approved flow meter is an economic combination of
orifice plate and bypass flow indicator using glass tube
variable area (VA) flowmeter for water flow measurement.
Suitable for mounting in horizontal or vertical fire sprinkler
supply lines, the meter has innovative installation options -
the orifice can be fitted between BS1387 or BS3600 flanges, or
the Firegroove unit fits the grooved couplings common in
sprinkler installations.
