Tracer® Electronic Flowmeters
Tracer®vm Base Flowmeter
The Tracer®vm Base Flowmeter is a non-display sensor that provides a 0.5 to 3.5 Volt output for process flow rate and a 0.5 to 4.1 Volt output for process temperature.
Vortex sensor technology is highly accurate and repeatable without moving parts. Flow reading is direction specific. Refer to the arrow on the body for correct installation.
Connection to the process is made using standard pipe threads in NPT or BSP from 3/8" through 1-1/2". Flow body materials are corrosion-resistant brass, nylon, anodized aluminum and stainless steel. The flowmeter is designed for use in industrial water applications such as injection mold cooling or filter and pump monitoring.
Tracer®vm Bluetooth Interface
The Tracer®vm Bluetooth Interface collects, transmits and saves data from Tracervm Base flowmeters installed in injection mold cooling circuits.
Flowmeters purchased separately are connected via cable to the Tracervm Bluetooth Interface. The Interface provides power to each flowmeter and receives voltage signals for temperature and flow.
The Bluetooth Interface wirelessly transmits flow rate and temperature to display on a mobile device. Flow condition data log files can be created via app and saved on USB flash drive documenting the mold cooling water conditions.
The Interface also communicates over Ethernet connection to PC software for network file storage and alerts. The files are easily read into database software for reference or analysis. Scientific Molders can use this data to confirm processing parameters and optimize cycle times and cooling water efficiency.
When used with PC software, a dry contact switch is available for connection to a peripheral or machine control to signal an alarm for out of limit cooling water conditions. Alerts are disabled when recording is not active.
Features and Benefits
- Transmits temperature and flow conditions in real time to mobile devices for process monitoring up to 20 meters away.
- Simplifies multiple Tracervm Base installations by providing power, ground and signal termination near the process.
- Gasketed, water-resistant plastic enclosure provides secure mounting in locations where occasional water spray is present.
- Housing mounting holes are integral for easy installation.
- Ethernet port connects the Interface to a local network for communication with Data Logger software.
- USB port provides mobile device charging plus flash drive connection.
- Free Android or iOS app and Smartflow Data Logger software.
- When used with PC software, dry contact switch signals out of limit flow conditions (temperature and flow rate).

TRACER®vm Electronic Flowmeter with User Interface Includes Programmable SPDT Switch, Analog Output, and FCI (Flow Characteristic Indicator) Technology with New Totalizer Function
Tracer®vm Electronic Flowmeter with User Interface employs reliable vortex shedding technology to monitor liquid flow rate and temperature. The newly-designed control circuit provides programmable switch set points for high or low flow or temperature and turbulent flow rate (FCI Technology). Analog Outputs for flow and temperature are selectable: 0.5 to 3.5/4.1V, 0 to 5V. or 0 to 10V, for connection to data acquisition system or PLC. A totalizing function is unique to this user interface with volume display from a selected point. Reynolds Number display and BTU’s per minute calculation are unique in the industry and come standard with this model.
Every unit is equipped with internal rechargable battery for temporary operation without attachment to direct power source. Standard cable is supplied with loose wire leads for customer termination. Optional AC wall adapter cable provides DC power for charging purposes. Optional cable is available for connection to RJG eDart System™.
This flowmeter may be ordered with remotely mounted electronics. The LCD Display and controls can be positioned up to 9.5 feet away from the flow body.
Sealed pushbuttons configure the flowmeter and switch operations through brightly colored LCD display and user-friendly menus. The SPDT switch can be wired directly to an alarm circuit in a process controller or other peripheral equipment such as low voltage stack lights.
NIST Traceable Calibration is available.
