Volume of water that went through the meter. Per sweep hand
revolution.
Protects the meter from debris in the line and corrects the
velocity profile of the flow to the meter.
Stainless steel assembly found on the outlet of the T-10
measuring chamber. It is used to regulate the flow that moves
through the T-10 chamber as the TRU/FLO's overall flow rate
increases. As the flow increases through the TRU/FLO, the
main valve assembly seals off the throttle valve. This helps
regulate the amount of flow moving through the T-10
measuring chamber.
Designed to register wide flow ranges where varying flow rates
are typical. It combines the low flow sensitivity of a disc-type
meter with the high flow capacity of a turbine-type meter.
Registers high flows.
Meters that have a rotating element that turns with the flow of
water. The volume of water is measured by the number of
revolutions by the rotor.
Unitized Measuring Element.
