Burger & Brown Engineering, Inc. Non-display Temperature Monitoring Vortex Flowmeters (Size 3/8” to 1-1/2”) TRACER®

The TracerVM Flowmeter is a non-display sensor that provides a 0.5 to 3.5 Volt output for process temperature and flow rate. Flow sensor technology is highly accurate and repeatable vortex shedding behind a bluff body. 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. Options based on thread size, see page 2 for details. The flowmeter is designed for use in industrial water applications such as injection mold cooling or filter and pump monitoring.

Tracer Electronic Flowmeter with Liquid Crystal Display (LCD) measures liquid flow rate, temperature, calculates BTU’s per minute and incorporates a new Flow Characteristic Indicator (FCI). 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. Annual calibration is recommended for best results.

Features and Benefits

• Bi-directional flow reading makes installation simple and convenient.
• English or Metric units for flow and temperature are userselectable.
• Corrosion-resistant wetted parts assure long-lasting durability.
• Polysulfone viewing window provides visual flow indication (DD-3B & DD-3E models only).
• Automatic display shut-off prolongs battery life.
• RoHS compliant

Automatically adjusts flow rate to user-selected value regardless of changes in line pressure. Includes Programmable SPDT Switch, Analog Output and FCI Technology.

Tracer®vma Electronic Flowmeter with AutoReg™ automatically adjusts the connected flow regulator opening, resulting in a more consistent flow rate and greater control over cooling water conditions without manual adjustments.

Automatic flow regulation compensates for changes in pressure that can occur during normal production due to in-line press startup or shutdown. The AutoReg responds quickly to maintain a steady cooling water flow rate essential for consistent molded part quality.

The flowmeter employs reliable vortex shedding sensor technology to monitor liquid flow rate and temperature. The 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 for connection to data acquisition system or PLC. The totalizing function and BTU’s per minute calculation are also included with this model.

This flowmeter may be ordered with remotely mounted user interface. The user interface can be positioned up to 9.5 feet away from the flow body.

Sealed pushbuttons configure the flowmeter and switch operations through bright color 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.

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 to 5 or 0 to 10 Volts, for connection to data acquisition system or PLC. A totalizing function is unique to this user interface with volume display from a selected point. BTU's per minute calculation is also included with this model.Tracer®vm with InterfaceEvery 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™.Sealed pushbuttons configure the flowmeter and switch operations through bright color 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.

Tracer Electronic Switching Flowmeter measures liquid flow rate and temperature while providing a selectable analog signal and programmable switch for low or high flow and temperature.

8 to 28VDC power source operates the flowmeter. Sealed pushbuttons configure the flowmeter and switching operations through user-friendly menus. FCI (see page 19) and BTU’s per minute calculation are standard.

Analog signal transmits 0 to 5 or 0 to 10 Volts; signal is scaleable for flow and temperature. The SPDT switch in the Tracer flowmeter can be wired directly to a process control system or other peripheral equipment. The NPT(F) threaded openings provide versatile, leak-free connections to match existing plumbing.

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. Not recommended for use with liquids containing metallic particles.
