Electronic Flowmeters
SMARTFLOW® Electronic Flowmeters are available in a range of sizes from 3/8" NPT to 2" NPT (F) inlet/outlet, and flow ranges from 0-8 gallons per minute to 10-110 gpm (0-418 lpm). TRACER® Electronic Flowmeter with Liquid Crystal Display (LCD) measures liquid flow rate, temperature, calculates BTU’s per minute, and indicates turbulent flow with the new Flow Characteristic Indicator* (FCI). View Details > TRACER® Switching Flowmeter with Programmable SPDT Switch measures liquid flow rate, temperature, turbulent flow, and calculates BTU’s per minute while providing one programmable switching set point for high or low flow or temperature.

* FCI (Flow Characteristic Indicator) Turbulent Flow is the point at which cooling efficiency is optimized. Flow rates higher than the point of Turbulent Flow do not improve cooling. Using FCI, systemic cooling water flow can be optimized, conserving water and maximizing cooling plant-wide with no plumbing changes. "TFLOW" displays when Turbulent Flow is present within the Tracer® Flowmeter.
