WATER METERS

Water Meters are used to measure the amount of make-up water added to a system. The Water Meter can be fitted with a dial readout or a contact head. The contact head will give a dry contact closure every predetermined number of gallons to signal a remote counter or timer. The timer can, in turn, be used to run a pump, solenoid, or other device. The make-up water can be treated based on volume through the Water Meter. The timer can be part of a remote pump control panel or is available as a Water Meter/Timer package. The timer in the Water Meter/Timer package is an Omron timer and is infinitely adjustable from seconds to hours. The timer contacts are rated at 10 amps, 1/4 HP, 120 VAC and are wired to a receptacle on the bottom of the timer enclosure.
