MICROFLOW

Product catalog summary

Technical Specifications: The MicroFlow is a non-contacting liquid flow velocity sensor utilizing microwave technology to measure flow velocity by analyzing reflected pulses. It is suitable for open channel flow applications without existing primary measurement devices and can be integrated with a Pulsar level transducer and controller for a complete system.

Physical Specifications: The sensor body measures 90 mm in diameter and 140 mm in height, weighing approximately 1 kg. It is made from Valox 357 material. The transducer cable can extend up to 500 meters, and the sensor can be mounted via a 1” BSP thread or a 20 mm adaptor, with an optimal mounting angle of 45°.

Environmental Specifications: The sensor is protected by an IP68 enclosure and operates within a temperature range of -20 °C to +60 °C. It holds CE, Radar, and ATEX approvals.

Performance Specifications: The velocity range is from 200 mm/s to 6 m/s, with an operational range up to 3 meters. Accuracy is the greater of ±0.5% or 50 mm/s. The sensor is optimal for channels up to 1.5 meters wide and operates on the K-Band with a transmitter power of less than 15 dBm.

Outputs: Communication is facilitated through RS485 and Modbus RTU, compatible with Pulsar FlowCERT or Ultimate controllers.

Programming: Programming is done via RS485 Modbus RTU with security through a passcode and data integrity maintained by non-volatile memory. The MicroFlow PC software is compatible with Windows 7/8/10.

Supply: The operating voltage is 10-28 V DC with a power consumption of 0.36 W. A 4-20mA loop powered version with ATEX Ex ia Zone 0 approval is also available.

Catalog excerpts

Technical Specifications: MicroFlow is a non-contacting liquid flow velocity sensor that uses microwave technology to transmit short pulses that reflect off a moving surface back to the sensor and are analyzed to determine the velocity. It is designed for open channel flow applications where the channel has no existing primary measurement device (e.g. weir or flume). Can be combined with a Pulsar level transducer and controller in order to provide a complete flow measurement system. Sensor Body Dimensions: Sensor Body Material/ Description: Transducer Cable Extensions: Mounting Connection: Via 1” BSP back-mounted thread or 20 mm (0.8 in) via the supplied adaptor. Optional mounting bracket available from Pulsar Mounting Angle: 45° optimal and mounted at the centerline of the channel with a clear uninterrupted view Maximum Separation: Enclosure Protection: ATEX Approval: Listed in the Certificate of Conformity within the manual. Velocity Range: Operational Range: Optimal Installation: Install at an angle of 45° in line with the flow. More information is provided within the manual — see the ‘Locating the MicroFlow sensor’ section Max. Channel Width Per Sensor: Transmitter Power: Beam Width: Compatibility with Pulsar Controllers: RS485 and Modbus RTU Integrates with FlowCERT or Ultimate
