Leaders in Water Treatment Control Equipment

JSJ Industrial MeterCarlon JSJ Electric Contacting Industrial Meters measure the water and provide a switch closure each time the pre-set amount of water passes through the meter. This signal can be used to actuate pumps, valves, alarms or other equipment involved in the processing system. These all bronze case meters are of the popular Carlon time-proven design…equipped with a cam actuated normally open 10 amp micro-switch and totalizing register. Used in conjunction with a Carlon Timer, Batch or Pump Controls the JSJ meter can provide a control of both the number of gallons desired per cycle and the length of the signal for pump operation, valve opening, etc. They can also be used in conjunction with other types of electrically-actuated water treatment controls.

Product Details

For longtime, trouble-free performance, the size of the meter selected should be based on the continuous flow in gallon per minute (GPM), not pipe size. The life of a meter will be greatly reduced if it is continuously operated at or near its maximum flow rate. The first step, therefore, should be to determine the continuous rate of flow in your system. For example, if this is determined to be about 25 GPM, a 1″ meter should be chosen rather than a 3/4″ size.
