The S-100F is composed by a digital converter and two clamp-on or insertion ultrasonic transducers. It is designed to measure the fluid velocity of a liquid inside a closed conduit. The transducers are a non-contacting, clamp-on type, which provide benefits of non-fouling operation and easy installation. The DSP digital technology (Digital Signal Processing) ensure a low sensibility of the instrument against potential transient factors. The size of the pipe may vary from 20 to 4000 mm (using different transducers), while the liquid can be: ultra-pure drinking water, chemicals, waste water, cooling...

The measurement technology used by the level transmitter METER is based on a short ultrasonic pulse. The ultrasonic wave propagates to the surface of the product to be measured, bouncing on the surface and back towards the sensor. The time interval between the sending and receiving wave is called the flight time and is proportional to the measured distance, therefore the level.
