Description
Tracer Model DDS Digital Display Switching : DD3-BB
General Information
Tracer Electronic Switching Flowmeter measures liquid flow rate and temperature while providing a selectable analog voltage and programmable switch. Tracer Switching Flowmeter calculates BTU’s per minute and incorporates FCI (Flow Characteristic Indicator) in support of Scientific Cooling principles.
8 to 28VDC power source is required to supply the flowmeter. Sealed push-buttons configure the flowmeter and switching operationgs through user-friendly menus.
Separate analog outputs facilitate data colelction of temperature and flow rates. The voltage outputs are user-selectable using on-screen menus: 0 to 5 Volts or 0 to 10 Volts.
FCI helps optimize systemic water usage. “TFLOW” on the digital display signifies the presence of Turbulent Flow, or maximum cooling water efficiency. 10,20 or 30% glycol mix is supported in Turbulent Flow Calculations.
SPDT switch is progrmmable for one to five set points: low flow, high flow, low temperature, high temperature and / or turbulent flow condition. Set points may be turned on or off in any combination.
Bi-directional flow reading makes installation simple and convenient.
Metric or English units for flow and temperature can be selected at any time.
Applications Tracer flowmeter is suitable for use in injection molding machine cooling water loops, lube oil systems, blending systems, filter condition indicators, and varied applications requiring flow measurement of clean, non-viscous, chemically compatible process liquids.
Annual calibration is recommended for best results. 3/8″ Trace flowmeters are not recommended for use in liquids containing ferrous particles.
