ORION ECHO 312 SERIES ULTRASONIC LEVEL TRANSMITTERS

Application

Orion Echo Ultrasonic Level Transmitters ( Sensor ) offer non-contact measurement of liquid and solid level and volume. The Ultrasonik level transmitter is four-wire type and uses keypad and LCD display to set up parameters of the level, distance and volume range to be measured. fault indication keeps you informed of the operational and fault status at the transmitter. Orion Echo is a cost effective, ultrasonic level transmitter for measuring and monitoring liquid levels in open and closed tanks. Its small size makes it compact, combining sensor and electronics in one housing. The sensor section is manufactured from Glass reinforced epoxy or  PVDF as an option. This PVDF material is resistant to most chemicals, and includes an on-board, temperature sensing element to ensure correct level measurement at all temperatures. The electronics housing is manufactured from aluminium.

  • The Ultrasonic Level Transmitter  ECH_312 series combines an ultrasonic sensor and a transmitter with a large 2x20-digit LCD display in IP68 cast aluminium enclosure.
  • The transmitter is powered with 15-30 VDC ; features a 4-20 mA output, RS485 Modbus serial port for PLC, or for monitoring and Hart communication for DCS systems.
  • Two relays can be configured as latched for automatic fill or empty operations.
  • The transmitter ECH_0312 series includes a range of fail-safe features. Signal loss, power supply failure, level alarm can be activated with an adjustable time delay.
  • A range of filter functions control the return echoes and automatically eliminate all interference.
  • 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 (liter, m 3 , imp. gal, U.S. gal).
  • The simulation functions allow the system to be tested under dry-run conditions. Applications.
  • Non-contact continuous level or volume measurement with all liquids in open or closed vessels.
  • Distance and movement supervision.
  • Waste engineering, water treatment and process technology.
  • Food industry.
  • Chemical and pharmaceutical industry
