Pulsar Measurement - Model MicroFlow - Non-contacting Microwave Liquid Velocity Sensor
MicroFlow delivers accurate, repeatable velocity measurement of liquid flow, either as a stand-alone device or as part of a complete measurement system. MicroFlow builds on Pulsar's award-winning pipe flow technology and world-leading open channel flow measurement systems.

MicroFlow can be installed as a stand-alone velocity sensor delivering data via RS485 Modbus or integrated within a complete system when combined with FlowCERT or Ultimate controller and dB series transducer.
Velocity x area calculation using MicroFlow provides a cost-effective flow measurement option compared to the installation of a primary measurement device such as a flume and provides a viable alternative where the hydraulics of the site do not allow for a restriction in the channel.

Contacting & Non-contacting Ultrasonic Instrumentation for Influent and Effluent Flow Monitoring - Water and Wastewater
Flow measurement of both the influent and effluent flows is used to determine the processes and operations within treatment works, to adequately treat the influent, and meet compliance of discharge. Accurate measurement also allows for the monitoring of the load to the works, effective storm overspill monitoring, and the measurement and future expansion to the works if necessary. Successful measurement of influent and effluent flow enables water companies across the globe to ensure that their works are running ...

Ultrasonic Level & Flow Instrumentation for Sewer Network monitoring Applications - Water and Wastewater - Sewer Cleaning
Sewer Network Monitoring involves monitoring level and flow within the sewer network to ensure that everything is running as it should be. Area-Velocity monitoring in these applications is particularly important as this helps give operators early warnings of potential blockages within the system. For example, a rising level without the corresponding rise in velocity indicates that something isn't right. Our non-contacting technology means there is no need to interrupt the network when it comes to installation, and ...

Ultrasonic Instrumentation for Flow Monitoring Applications - Mining
During many different processes throughout the metals and mining sector, there is often a lot of excess production of water. Some of this water may indeed be wastewater and will need treating before being discharged back into the environment. Pulsar Measurement offer a range of different flow solutions, from open channel flow, to full and partially filled non-contacting pipe flow. Some of the discharge may be required to be measured to an MCERT standard and we are proud to supply a number of accredited ...
