Ultrasonic Level Transmitter

Ultrasonic Level Indicator

The EA ultrasonic level indicator is a robust level measuring device for industrial applications. This non-contact type level transmitter is not only low cost and easy to install but it is a low maintenance level measuring product too. 

Highlights

• Compact – EA is a compact ultrasonic level transmitter that has 3 push buttons and is operated in 8 parameter mode and LCD display.
• Ease of Use – Flexible configuration for level or distance in meters, unit in feet or inch with zero and span calibration at any two points.
• Quick Response – The ZMICROFLEX-C compensates the Doppler's effect internally and makes the difference with other competitor's products; it can detect level moving up to 10 m / min without signal loss.
•  Hazard Areas and Corrosive Applications – This ultrasonic level indicator can be used in extreme plant conditions too. ATEX Hazardous area approved units are available for use in Zone Zero environments. The PVDF transducer is ideal for use in corrosive applications.

Applications

This ultrasonic level transmitter is used for level measurement, volume measurement, object distance measurement and pump control. The common applications of this reliable ultrasonic level transmitter include:
•    Water or waste water treatment equipment: for instance, pump, open channel, dams and wells.
•    Liquid such as edible-oils, sauces, diesel oils and beverages.
•    Chemical material such as solvent, paints, carbonic, water, crude oil, epoxy resin, lime slurry and wax.

Principle of Operation
During in operation, the ultrasonic wave firstly emit to the measured medium level. When the ultrasonic wave reaches the surface and reflects back to the transducer, the time interval between transmission and reception will be converted to the physical parameter like the medium level or distance between the ultrasonic level indicator and medium surface. The formula is D= (334.1+0.6t) x T/2, where the D = the transmission distance; t = temperature; and T= transmission time. ZMICROFLEX-C is a compact device which consists of electronic component and transducer. With 4~20mA output, it can be connected to the PLC,DSC and SCADA system. Besides that, it is also equipped with exclusive PULSE and AGC (Auto Gain Control) echo tracking technology to ensure accuracy and precision even in the harsh environment.
