ALSONIC-DDPL

ALSONIC-DDPL Ultrasonic Flow Measurement

SmartMeasurement's Alsonic DDPL doppler flowmeters employ a pair of clamp-on or fixed-type transducers combined with a powerfull flow computer for non-invasive liquid measurement. The enhanced ultrasonic Doppler flow measuring technique employed by the ALSONIC-DDPL makes it an excellent choice for measuring solids-bearing or aerated liquids in metal or plastic pipe. Clamp-on or insertion transducers allow the system to be installed in minutes without interrupting the process flow while providing low installation costs.

The ALSONIC-DDPL's combination of advanced features and available options will provide superior value for many solids-bearing liquid flow measuring applications including those found in wastewater and the pulp & paper industry.

Non-fouling transducer is immune to build-up of grease, paraffin and other coating materials
Solid-state measurement technique never requires re-calibration and is virtually maintenance-free
Lower straight-run requirements vs. other flow measurement technologies
Industry standard outputs allow direct interface to data loggers and control systems
Data logger function; includes date, totalizer, signal condition
Operates with relatively clean liquids as well as liquids with high concentrations of suspended solids or aeration
Alphanumeric keypad display for field setup with two-line, backlit display; indicates instantaneous and totalized flows
