System Overview

Nowadays, one of the important challenges in industrial process control, is level measurement. The most of present level meters are contact based and do not provide accurate results. One of the most reliable and contact-less level gauge for liquid application is Ultrasonic level transmitter.

RSCO Ultrasonic level transmitter is designed to use for wide range of applications with non-contact control. Another feature of this product which creates reliable level measurement solutions are water and dust proof. Some application of this product is chemical, food, Pharmaceutical and water.

RSCO Ultrasonic level transmitter is designed based on TOF (Time Of Flight) principle. Measurement process is done over following steps:
- emitting a high-frequency pulse by sensor
- The pulse impacts the level surface and is reflected back to the sensor
- Receiving the reflected pulse
- Transmitting the pulse and its echo to processing unit separately
- Computing the time intervals between send and receive signals
- Measuring speed of sound in consideration to operating temperature
- Computing the distance to the medium surface in consideration to computed time and speed of sound
