ECHO 306, 312, 318, 324 Series Ultrasonic level sensors

FEATURES Linearity %0.2 Max Measuring Distance 6m ( Liquid surface ) Min Measurement Distance 0,2m

FUNCTIONS

Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high

frequency (30 kHz to 75 kHz) acoustic waves that are reflected back and detected by the emitting transducer.

Ultrasonic level sensors are also affected by the changing speed of sound due to moisture, temperature and pressures.

Correction factors can be applied to improve the accuracy of measurement.

FEATURES AND APPLICATION AREA

• The transmitter is powered with 24 VDC; features a 4-20 mA output, RS485 Modbus serial port for PLC, or for monitoring

• The transmitter ECH-0300 series includes a range of fail-safe features. Signal loss, power supply failure, level alarm can be activated with an adjustable time delay.

• Easy and fast commissioning is guaranteed with the “Simulation” functions. Different tank shapes (cylindrical, cubic, spherical) can be easily programmed via fixed default shapes .

• The measured value can be shown as level, distance (in cm, m, inch or feet), or direct as volume (litter, m3, Imp. Gal, U.S. Gal).

• Waste engineering, water treatment and process technology.

• Food industry.

• Chemical and pharmaceutical industry.
