Gallon Meters

Fleck Gallon Meters provide a high-efficiency method of monitoring water usage and initiating timely regenerations; resulting in salt, water and energy savings. Meters range in size from 3/4” – 2” and are designed to fit commercial, industrial, and large-volume residential applications.

Automatic regeneration takes place as an immediate or delayed timer is triggered by a time clock set for certain days and time of day or a remote PLC giving a signal to the timer or by a gallon meter located on the soft water side of the valve or valves.  Refer to System Choices to see how gallon meters can be used on single or multiple tank systems.

The meter bodies on industrial commercial valves come in sizes from 1” to 3” in either brass bodies or stainless steel. The picture of this mechanical gallon meter shows a brass meter body with a black meter dome.   When attached to the valve or a remote meter timer this dome would have a black cable linking it to the gallon wheel on the front panel of the mechanical timer or a wire plugged into the digital timer circuit board.  In the case of a mechanical meter the dome can be standard range or extended range.  The extended range meter dome will register about 5 times more gallons than the standard range meter dome.  Both domes must be matched with the appropriate volume label on the gallon meter wheel, see the attached picture showing the numbers 0 to 100 x’s 100.  This mechanical wheel will register slightly more than 10,000 gallons of soft water before a regeneration is cued.  Notice the white dot on the outside of the number ring pointing to about 98.  This white dot is the set point (98 x’s 100= 9,800 gallons) at which regeneration is cued to begin.  The white dot and number wheel will move counter clock wise as water is used and the “Capacity” triangle points to the number of gallons remaining before regeneration.  In the digital timer dome (NXT for example) the gallon range is 0 to 999,999 gallons and the gallons remaining is displayed on the digital screen.  All meter set points are to be calculated to the amount of resin extraction capacity in the tank and water hardness.

It is common for older control valves to be changed out from mechanical to digital with a complete new valve or a simple power-head change.  The mechanical meter dome can easily be replaced with a digital meter dome eliminating the need for a complete new meter body.  If a gallon meter unit quits counting gallons it would often point to a new meter dome as the fix.
