Smartflow Tracer VMA Series Operating Instructions Manual

Tracer with AutoReg™
®
VMA
Flowmeter with Automatic Flow Regulation
Operating Instructions

General

The Tracer Flowmeter with AutoReg provides:
VMA
• Analog Flow Output (Selectable 0 to 3.5V, 0 to 5V or 0 to 10V)
• Analog Temperature Output (Selectable 0 to 4.1V, 0 to 5V or 0 to 10V)
(Lowest Voltage Output settings match Tracer
of direct replacement if needed.)
• Programmable Alarm Switch for High or Low Temperature and/or
Flow. Switch can be set for Turbulent Flow instead of programmed
settings. 1A, 30VAC/30VDC
• Flow Rate Display (GPM or LPM)
• Fluid Temperature Display (°F or °C)
• Reynolds Number Display
• BTU's per Minute Display
• FCI Display (Turbulent Flow or "TF" on display)
• Volume Totalizer Display
• Automatic Shutoff Timer
• Glycol Scale Options, 0%, 10%, 20% or 30% (for FCI Calculation)
Automatic Regulation Control Features
• Regulation via Flow Rate or Reynolds Number
• Actuator Alarm notifies user via switch when the AutoReg is unable to
achieve the desired set point (15 seconds - 999 seconds).
