Product Description

UGS quartz tube level gauge is consist of high purity quartz glass tube, meter shell    and. explosion-proof  valve,  with  red  displaying  height  of  liquid  and  green  for  height  of  vapor phases.  The  advantages  are  clearing  reading,  observation  direction  adjustable,  simple structure,  reliable  work,  and  night  view  with  light  source  etc.  It  is  easy  cleaning  and maintenance.  Once  quartz  tube  happened  to  explosion,  steel  ball  in  the  valve  can automatically block fluid channel to reduce or avoid accidents.



1. Clear indication, good sealing

2. High working temperature: ≤+450°C

3. High working pressure: ≤PN100

4. Long lifetime, simple structure, easy cleaning and maintenance

5.There are two steel ball in the valve at the both sides. When quartz tube happened to explosion, Steel balls can automatically block channel to avoid liquid flow away if the pressure difference between inside and outside is above 0.3Mpa.



1.Single color quartz tube level gauge

2. bi-color quartz tube level gauge

3. Non-blind area bicolor quartz tube level gauge

4. Anticorrosive bicolor quartz tube level gauge (polypropylene, PTFE lining)

Working principle: It consists of two parts: a magnetic indicator and a float. The magnetic indicator is composed of a red and white magnetic flipping column or a magnetic flipping card and a guard plate equipped with a small magnetic steel. When the floating ball equipped with magnetic steel moves up and down with the liquid, the beam magnetic field of the permanent magnet in the floating ball turns the magnetic turning column 180°. When the liquid level rises, the turning column turns from white to red. It turns from red to white to indicate the height of the liquid level. (The color of the flop and the flop can be different, such as blue and red or black and white, etc.). When it is necessary to transmit output, install a reed switch or magnetic sensor transmitter parallel to the magnetic indicator to realize the remote transmission of 4-20mA or 0-10mA current signal; equipped with a liquid level alarm switch, and The upper and lower limits of the liquid level can be alarmed.

Feature: In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and control switches with complete detection functions. The indication is novel, the reading is intuitive and eye-catching. The indicating mechanism is completely isolated from the measured medium, so it has good sealing, high reliability and safe use. The structure is simple, the installation is convenient, and the maintenance cost is low. Corrosion resistance, no power supply, explosion-proof. According to the different installation positions in the container, there are two types of side mounting and top mounting.
