Product Description

UGS series double-color quartz tube liquid level meter is composed of high purity quartz glass tube, explosion-proof angle valve, body and so on. The height of liquid and gas phase is shown in red and green respectively. It has the advantages of clear display, direct viewing, adjustable observation direction, simple structure, reliable operation and night observation with light source. Quartz liquid level tube can be easily wiped or flushed, angle valve in the steel ball in the quartz tube position accidental explosion automatically blocked the fluid passage, 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.

Workshop and Procesing

Water Meter Accuracy Oil Level Sight Glass 3


Water Meter Accuracy Oil Level Sight Glass 4


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.
