Measures liquid flow rate, temperature, calculates BTU’s per minute, and Turbulent Flow. The highly-visible display is configured via the sealed push buttons and user-friendly menus.

As a diagnostic tool, engineers and maintenance personnel can quickly spot-check temperature and flow in water lines using the LCD TRACER flowmeter. This portable LCD unit is unmatched as a troubleshooting tool. As a process control tool, the TRACER can be left in place to closely monitor more critical applications. The adjustable, automatic shut-off feature prolongs battery life.

NIST Traceable Calibration is available.

FCI (Flow Characteristic Indicator) Technology

Turbulent Flow is the point at which cooling efficiency is optimized. Flow rates higher than the point of Turbulent Flow do not provide proportionally increased cooling improvement. Using FCI Technology, systemic cooling water flow can be optimized, conserving water and maximizing cooling plantwide without plumbing changes. “TFLOW” displays when Turbulent Flow is present within the Tracer flowmeter.
