Pulsar’s MicroFlow Non-Contacting Liquid Velocity Sensor – Maintenance-free and Cost-effective

UK measurement specialist Pulsar Process Measurement’s latest launch is MicroFlow, a microwave based non-contacting velocity sensor that mounts simply above a channel to provide maintenance-free, reliable, repeatable and accurate velocity measurement.

2016 05 17 102800For flow volume measurement, velocity x area provides a cost-effective alternative to a channel restriction such as a flume, and a viable solution in situations where system hydraulics do not permit the installation of any primary measurement device.

MicroFlow can be used as a stand-alone device, outputting velocity data via RS485 Modbus with a measurement accuracy of ±0.033m/s or 0.5%, whichever is greater. The industry-standard data can be used for datalogging or alarm purposes, or processed further in a PLC. MicroFlow can also integrate with Pulsar’s FlowCERT ultrasonic flow measurement controller and a transducer such as Pulsar’s flow-dedicated dBMACH3 to create a complete open channel flow measurement system.

MicroFlow consists of a compact, lightweight low-cost sensor, and is simply installed on a bracket above the flow at a 45º angle. Loop power and straightforward RS485 PC set up means that connection is simple and quick. Signal processing is via Pulsar’s well-proven digital algorithm and is a development from the system first seen in their award-winning FlowPulse device for measurement in closed pipes.

Pulsar Process Measurement are the leading international specialists in non-contacting acoustic and ultrasonic technology for level measurement and control, and flow measurement in both open channels and closed pipes. From a base in Malvern, UK, they have developed sensor and software technology that allows them to measure in difficult applications, becoming the world’s leading specialist manufacturer of ultrasonic level measurement instruments. They also offer a range of sludge interface monitors, clamp-on pipe flow meters and open channel flow and velocity sensors. For more information, please check the website
