Overview：

     The Pulsation Series ET was designed to feed chemical in response to a water meter input.

When the count exceeds a set value (either 1 or 10), the pump starts. The pump will continue

to run for an adjustable time period. The Series ET includes both input and output water meter

connections at the front panel. The output connection provides an isolated dry contact output

of the water meter contact to operate additional pumps or timers off the same water meter.

Typical applications include inhibitor feed for an open air-cooling tower. The Series ET

provides everything you need in one unique, compact package to create a simple and cost

effective metering system.
    

     Fourteen distinct models are available, having pressure capabilities to 250 psi (17 bar)

@ 5 gpd (0.8 lph), and flow capacities to 504 gpd (79.5 lph) @ 20 psi (1.3 bar), with a

turndown ratios up to 100:1. Metering performance is reproducible to within ± 2% of maximum

capacity.
