Econ Stennicator Meter System

Pulse water meter activated 1:128 medicator injection system

Ideal for Convenient and Quick Installations or Turnkey Operations

Saving time is a plus for busy farmers and the Econ Stennicator Meter System is pre-assembled with the Econ Stennicator pump and water meter mounted on heavy duty panel.

The Econ Stennicator is Stenner’s medicator for injection at the fixed ratio of 1:128. The pump runs on electricity and is activated by a dry contact, pulsing water meter.  If using a house controller, the pump’s internal relay repeats the water meter signal to the house controller so water consumption continues to register.

Not a Traditional Medicator

Traditional medicators and proportioners are typically hampered by poor water quality or the water bypass that can restrict water flow. In addition, some aggressive solutions attack the internal working parts of the water driven pump.

The Stennicator does not restrict flow, the pump injects at the 1:128 ratio straight into the water line. The chemicals injected are contained in the peristaltic pump tube and the suction and discharge lines and do not touch the moving parts in the pump. Like all Stenner peristaltic metering pumps, the Stennicator is self-priming with no loss of prime due to gaseous solutions.

The system water meter is available in 3/4″ or 1″ with pulse rates of 1 or 10 pulses per gallon or 1 pulse per liter. The single system is best for water flow rates up to 2.7 gallons per minute (162 gallons per hour). The dual system includes two pumps to keep up with water flow rates up to 5.4 gallons per minute (325 gallons per hour).
