Product Description

E+H Ultrasonic measurement Time-of-Flight Prosonic FMU40 Ultrasonic Level Transmitter

The Prosonic FMU40 operates on the time - of - flight ultrasonic principle. The sensor emits ultrasonic pulses towards the surface of the substance being measured, whether it's a liquid, paste, or bulk solid. These pulses travel through the air or other mediums in the measurement environment. Once they reach the surface, they are reflected back to the sensor. The transmitter within the FMU40 precisely measures the time it takes for the pulse to travel to the surface and return.

The e+h Prosonic FMU40 is a cost - effective and versatile device designed for sophisticated level measurement in liquids and bulk solids, with a maximum measurement range of up to 5m. Leveraging advanced ultrasonic time - of - flight technology, it offers reliable and accurate measurements in a variety of industrial applications.

Field of application:

Benefits:

The Prosonic FMU40 sensor is suited for non-contact level measurement in fluids, pastes, coarse bulk material and flow measurement in open channels or at weirs. The two-wire or four-wire compact transmitter can be used in applications with storage tanks, agitators, on stockpiles and conveyor belts. The envelope curve can be shown on the on-site display for simple diagnosis. Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate.

Two-wire or four-wire instrument for continuous non-contact level and flow measurement.

6.Calibration without filling or discharging
7.Integrated temperature sensor for automatic correction of the temperature dependent sound velocity

Compact and Versatile Design: 

High-Precision Measurement:

User-Friendly Operation: 

The FMU40 is available in both two - wire and four - wire configurations. This flexibility allows it to be easily integrated into different electrical systems, whether in simple setups where a two - wire connection suffices or in more complex installations that require the additional functionality provided by a four - wire setup.

The device offers an impressive accuracy of ±2mm or ±0.2% of the set measuring range. This high level of precision makes it suitable for applications where even the slightest deviation in measurement can have significant consequences, such as in pharmaceutical manufacturing, where accurate level measurement of raw materials and products is crucial for quality control.

It features a four - line plain text display with 7 languages selectable. This makes it accessible to operators from different regions and language backgrounds. Technicians can easily understand the measurement data, configure settings, and receive diagnostic information, reducing the learning curve for new users and enhancing the overall user experience.
