Ultrasonic Flowmeter
-------------------
Manufacturer: SMC(USA)
Model: ALSONIC-DDPL Series
Introduction:
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.
Features:
- 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
