The AVFM 5.0 Area-Velocity Flow Meter measures both Level and Velocity to calculate flow in an open channel, partially full sewer pipes, and surcharged pipes without a flume or weir. Calibration is simple: enter the pipe diameter or channel dimensions and the AVFM 5.0 automatically computes and displays flow volume.

The AVFM 5.0 has been replaced by the AVFM 6.1 Area-Velocity Flow Meter, which offers enhanced performance and optional Modbus RTU Output.

The Blackbox blind non-isolated version was designed for anyone who needed a simple straight forward level indication. With no display, it was ideal for those applications where power was scarce and it could be programmed via a handheld calibrator or Blackbox PC Software.

The unit has now been replaced by the Blackbox 130 display version, which can be programmed via its integral keyboard and provides an output representative of volume.

The DFM 5.1 Doppler Flow Meter monitors the flow rate of dirty or aerated liquids including wastewater, chemicals, acids, slurries, abrasives, and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles. The sensor is mounted on the outside of a plastic or metal pipe 12.7 mm (0.5 in) diameter or larger.

The DFM 5.1 has been replaced by the DFM 6.1 Doppler Flowmeter, which offers enhanced performance and now has as an option Modbus RTU or HART.

The OCF 5.0 uses a non-contacting ultrasonic sensor mounted over a flume or weir to measure flow. It is accurate, reliable, and verifiable. The separate, watertight electronics/display enclosure can be mounted within 150 m (500 ft) of the sensor. The OCF 5.0 continuously displays, totalizes, transmits and data logs open channel flow.

The OCF 5.0 Open Channel Flow Monitor has been replaced by the OCF 6.1 Open Channel Flow & Tank Level Meter, which offers expanded flume & weir selections or level tank monitoring, and it also has optional MODBUS RTU Output.

The SLT 5.0 Level & Flow Monitor, displays, transmits, and totalizes wastewater flow through any flume or weir. Each SLT 5.0 includes a non-contacting ultrasonic sensor that mounts above the liquid being measured. Select flow mode for open channel applications or level mode for tank inventory, level control, and alarms.

The SLT 5.0 Level & Flow Monitor, has been replaced by the OCF 6.1 Open Channel Flow & Tank Level Meter, which offers expanded flume & weir selections or level tank monitoring and it also has optional MODBUS RTU or HART Output.

The TTFM 1.0 Transit Time Flow Meter is designed for flow measurement of fairly clean, nonaerated liquids in full pipes. The clamp-on transducers can be mounted without system shutdown. There is no pressure drop and no obstruction.

The TTFM 1.0 has been replaced by the TTFM 6.1 Transit Time flowmeter, which now offers pipe sizes as low as 12.7 mm to 1.2 m (0.5 in to 48 in) and has optional Modbus RTU or HART.

Ultra 3 combines several full-function, world-beating ultrasonic level measurement instruments into one. Full control functions are available: open channel flow is calculated to BS ISO 1438 and 4359. Pump Control features are built into Ultra 3 and an extensive set of volume calculations and linearisation facilities are available for a tank or silo level measurement task.

The Ultra 3 has been replaced by the Ultra 4 which offers the extra relay and the ability to combine three specific duties in one compact and cost-effective control package.
