Introduction to FM-200 Series Ultrasonic Liquid Level Gauge

Integrated design, easy to install
Three wire wiring ensures strong sound wave emission and stable and reliable measurement
Overvoltage and overcurrent protection, lightning protection
4-20mA output with optoelectronic isolation
Dual relays that allow larger currents to pass through are used for pump control or alarm
Failure protection, current output 22mA
Large display window with LCD or LED for easy debugging and observation
Advanced self clamping terminal blocks ensure that the wiring is never loose
Intelligent signal processing technology ensures that instruments adapt to various working conditions
Full plastic casing (IP68), acid and alkali resistant, suitable for harsh environments
Flexible bracket or flange installation
Application scenarios
Storage tank, chemical tank, open pool, material tank, water channel, water well, grain silo, material bin, channel
If a sealed container requires flange installation, the inner wall of the flange connection on the container should be smooth, and its lower edge should be a smooth circular arc shape. The inner diameter of the connection should be greater than 120mm and the length should be less than 100mm. There are no above requirements for the installation using a tube.
Simple bracket installation can be used in other places.
Outdoor applications in cold regions should prevent the surface of the level gauge probe from freezing. If it is an open container, it is recommended to use HLU20 (E) and HLU30 (E) level gauges. If it is a closed container, an extended probe type split level gauge can be used (the probe penetrates deep into the container).

FM-200A Ultrasonic Liquid Level Gauge

Product Technical Specifications
Tested medium
Clear water, sewage, mortar, mud, acid-base liquid, chemical reagents, fertilizers, pharmaceuticals, lubricants, heavy oil, asphalt, mineral solid particles
Technical confirmation is required for powdery solids.
For liquid, if its volatility is very strong, or it is easy to produce foam, fluctuates greatly, and there is a floating ball on the surface, the effective range will be reduced. It is recommended to select a level meter with a larger range.
