Description
The cast iron Wyatt Lo-Loss® meter is a differential-producing
flow tube that maintains its accuracy over a wide range of flow
rates. The hydraulic shape of the PMT Lo-Loss® meter incurs
a lower permanent pressure loss than any other differential producing
flow device. The PMT can be provided with either 125 or 250 PSIG
flanges.
Application
The cast iron PMT series of Lo-Loss® meters is designed to accurately
and reliably measure the flow rates of water, wastewater, sludge,
slurries, clean fluids, and gases in full pipe conditions. The PMT
series of meters is ideally suited to applications where permanent
pressure loss must be kept to a minimum, such as in gravity-fed
systems, or where a savings due to lower pumping costs can be realized.
The Model PMT-C is designed for rate-of-flow control applications,
while the PMT-S incorporates a rugged design for cleaning the pressure
taps for solid-bearing fluids.
Flow Measurement Accuracy
For pipe Reynolds numbers greater than 100 000 and in a normalized
piping configuration, the Wyatt PMT Lo-Loss® provides
a flow measurement accuracy of ± 0.25% with independent flow
calibration and ± 1.00% without flow calibration. Lo-Loss®
is a registered trademark of Wyatt Engineering.
