A Programmable Microwave Velocity Meter
Model HPVM 5
The HPVM 5 Motion Meter is a stand-alone, compact unit that emits a microwave signal to provide continuous velocity and magnitude measurements. Despite its compact design, the HPVM 5 has big advantages. Our new Motion Meter was engineered to include the following exceptional features:
The Motion Meter's powerful processing board, with 4–20 mA output and two programmable relays, allows utilization of the HPVM 5 as a process protection device for events such as motion-out-of-range or motion failure.
Users are able to program the operating parameters of the HPVM 5 either locally, using the intuitive 4-button/4-digit LED interface, or remotely, via the RS232 serial port. The port can also be used to download new or custom sensor/control programs from our Web site, or to diagnose and service the meter.
The sensor of the HPVM 5 is ideally suited for velocity and magnitude measurements of bulk materials moving in, or on, pneumatic conveying lines, belt conveyors, gravity spouts, chutes, discharge orifices, and so on. It is also suited for non-contact velocity measurements of moving machinery, such as fan blades, drills, blowers, and elevators. In addition, the HPVM 5 can be used for measuring frequency and amplitudes of vibrating equipment.
During operation, the velocity meter emits a low level K-band microwave signal that, when reflected off moving particles or objects, causes a shift in the frequency proportional to the velocity (Doppler effect). This reflected signal is processed by the sensor to provide continuous velocity and magnitude measurements. No calibration is required, by virtue of the Doppler effect and the design of the sensor. By allowing users to adjust parameters controlling the sensor's operation, the infinitely variable 4–20 mA output, and the programmable relays, the HPVM 5 is extremely flexible and provides a wide range of operating configurations.
