LUPS is an ultrasonic vibrating liquid level warning device. The device protects pumps from dry start, controls overflow, minimum or maximum liquid level with millimeter accuracy in the capacities of industrial facilities of food, pharmaceutical, chemical, petrochemical and other industries. The multi-point version of the device, in addition to the maximum and minimum, controls a number of predetermined intermediate values of the liquid level, which in some applications replaces an expensive level gauge.
The device is used to detect both the presence and absence of liquid. The operation of the detector is not affected by vibrations, turbulent flows, foam and solids in the working environment. Resistant to changes in density, dielectric constant, electrical conductivity, temperature and pressure.
Interacting with a controlled environment, the sensing element is made of stainless steel and is connected via a steel waveguide to an electronic circuit, all elements of which are outside the working area. Such a constructive solution allows working with a liquid in the temperature range -200 - + 500С and withstanding a pressure of 450 bar.
With the help of a magnet, it is possible to configure the device directly at the facility in the explosive zone: change the delay time of the alarm; switching of the operation mode - upper or lower level; sticking sensitivity selection; accurate calibration of the “dry” and “wet” state of the sensor.
LUPS-1 is a miniature universal liquid warning device.
LUPS-8 is a multi-point multi-purpose liquid level warning device.
