A look at the Tracer VM Flowmeter from Smartflow
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 the 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.
