ULM70 Ultrasonic level indicator Riels Instrument Vietnam

The ULM70 Ultrasonic level metersare compact measurement devices including an electroacoustics converter, central processor unit and display module.
Using the electroacoustics converter, the level meters transmitthe sequence of ultrasonic pulses that spread towards the surface level.
The converter recuperates reflected acoustic waves that are subsequently processed in the electronic module.
The intelligent evaluation block filters out interfering signals, compares the cleaned received signal with the false reflection map (e.g. from mixers, ladders, reinforcement etc.) and selects a suitable reflection (echo).

Based on the period during which the individual pulses spread towards the surface level and back and based on the measured temperature in the tank, the instant distance to the surface level is calculated.
According to the level height, the level meteroutput is set and the measured value is displayed on the display.
The Ultrasonic level metersare suited to level measurement of various liquid materials, sewerage waters, mash and paste materials, suspensions in closed or open vessels, sumps, reservoirs and open channels.
In case the level of bulk-solid materials is measured, the measurement range is reduced.

Features:

• For continuous non-contact level measurement
• Suited to level measurement of various liquid and bulk-solid materials
• Outstanding contrast OLED display
• Easy adjustment without measured material
• Quick view measured values on the display
• Current output (4÷20 mA) with HART communication protocol
• On request Atex version for usage in explosive areas
