SEB Low Flow Water Meter by Seametrics

SEB Low Flowmeter by Seametrics @ Procon Instrument TechnologyThe SeaMetrics SEB Low Flow Water Meter with High Output Pulse rate is used in industrial control operations.

The SEB is a plated brass low flow meter that is suited for clean water. It is available in 1/2” and 3/4” thread, with union-type meter couplings for easy installation and service.

This meter is ideal for flow rates between 0.2 and 18 GPM. The SEB has only one moving part, the propeller.

The 5-30 Vdc current sinking pulse output makes the SEB ideal for many industrial control applications. This signal interfaces easily with programmable logic controllers and computer input boards. SEB meters can also be used in conjunction with the Seametrics FT420 flow computer for reading flow rate and total flow, or AO55 for 4-20 mA output. For metering pump pacing applications, a standard PD10 pulse divider is recommended.
