Flow Technology releases ultrasonic, bi-directional liquid flow meter

The SLF-500 is a clamp-on ultrasonic meter capable of measuring bi-directional flow through metal, plastic and even lined pipes without altering the piping.

The SLF-500 was designed with the latest solid-state technology, providing the economic benefit of uninterrupted service. The meter has no moving parts reducing its cost of ownership and eliminating
common maintenance requirements and does not intrude into the proces line.

The SLF-500 employs digital signal processing (DSP) techniques for outstanding accuracy and repeatability (±0.2%).  The ultrasonic flow measuring device has no pressure drop and provides fast speed-of-response. The same unit can be used on line sizes from 1 to 12 in without recalibration, and covers a wide range of flow rates.

Typical applications for the SLF-500 include corrosive chemicals in the process industry, DI water and chemicals in the semiconductor market, fluids in the sanitary industry, or any installation when it is preferable not to have an instrument exposed to the process fluid.

Integral to the display unit, the set-up software leads the installer through a series of questions related to pipe material and size, display configuration and desired outputs. This makes the initial installation/reconfiguration for different applications a straightforward process. The sensors are provided with a robust mounting fixture allowing adjustment of the sensor mounting position for optimum performance. Sensor separation distance is determined and displayed on the SLF-500 during the
initial system set up.
