 Closed Pipe

Closed Pipe Flow Meters 

Measuring flow rate within a closed pipe can be achieved with many different metering technologies.  Pipe size, fluid type and velocity are important factors when selecting the appropriate meter for your measurement application.  Magnetic Flow Meters, Acoustic Doppler Insertion Meters and Ultrasonic Transit Time Meters are the most common meters used in the industry.  For more information and to speak with a representative within the states of Texas, Louisiana, Mississippi, Alabama or the Panhandle of Florida, please use the contact form or call our 24 hour product support number.

Hot Tap Acoustic Doppler Flow Meter (ADFM)
Closed Pipe Flow Measurement

The ADFM® product family uses exclusive pulse-Doppler velocity profiling technology to measure the velocity distribution within the flow, delivering advanced flow measurement performance.

This capability makes ADFM flow meters exceptionally versatile - and the most suitable choice for metering sites at large pipes and open channels, particularly those with non-uniform, rapidly changing, backwatered, near zero, zero, or reverse flow conditions.

Single Channel Portable Flow Meter

The FLUXUS F401 is FLEXIM's dedicated single channel portable flow meter for applications in the municipial water and wastewater sector offering long term stable and precise bidirectional flow measurements in remote areas outdoor - being ideal for water loss activities prescribed in AWWA M-36.

As the measurement is carried out from the pipe wall outside and without contact with the water column, there is no need to enter the piping system or to interrupt supply. Thus, the FLUXUS F401 is the ideal tool for service and maintenance activities, for long or short term monitoring, data logging and existing meter verification.

The FLUXUS F401 is equipped with water-tight IP68 / NEMA 6P transducers, with the flow transmitter residing inside a IP67 / NEMA 6 suitcase. Combining its internal battery capacity with an additional external battery suitcase (IP67 / NEMA 6 protected), the F401 offers long term remote measurements of at least one week.

The Portable Multi-Functional Flowmeter

The FLUXUS F601 is the portable clamp-on flow meter of choice for servicing and maintenance activities, the control and auditing of measurement points not covered by permanent meters, or even the temporary replacement of permanently installed flow meters.

The FLUXUS F601 is measurement-ready in less than 5 minutes, including the measurement of the pipe wall thickness, the connection of the transducers to the transmitter, the setup of the flow meter and finally the mounting of the transducers.

Bi-Directional Flow Measurement 

The FLUXUS F501 is FLEXIM's solution for many flow metering applications found in the water and wastewater sector and adjacent industries.

The FLUXUS F501 offers a precise bi-directional flow measurement over a wide turndown ratio - not only at high, but especially at low flow velocities. Due to its matched and paired transducers, it also guarantees a superior zero stability.

As of its high repeatability, the FLUXUS F501 also offers the possibility for leak detection. Especially at night, when temperatures are more even and only low flow velocities are common in drinking water lines, leakages can clearly be identified and such reading transferred to a process control system.
