According to many data from the previously recorded level gauges, most of them are explained separately. This article sorts out some of the articles about instrumentation, not just the overall article of the level gauge, because sometimes it is also necessary to proceed from the whole. Below, please see the main features of the dozens of level gauges contributed for everyone. Summary: Due to the limitation of the number of words in the article, the characteristics of various liquid level meters are introduced so much, because it is an introduction, so the length of the article is limited.

1) Ultrasonic level gauge | Level gauge: Digital level controlled by microprocessor - level meter, medium is almost unlimited, can be applied to complex working conditions of various liquid and solid material height measurement, can be realized Temperature compensation of measured values. Non-contact measurement, high measurement accuracy, simple operation, and intuitive interface.
2) Static pressure level gauge: The product is compact, light, sensitive and high performance, and has convenient installation and use. Mainly used in urban water supply and drainage, water treatment plants, reservoirs, rivers, oceans, oil storage tanks, tanks filled with paste and liquid level in petroleum, chemical, metallurgical, electric power and other departments and liquid levels of other open container liquids The measured liquid, whether water, oil, acid, alkali, salt or viscous liquid, can be measured with high precision.
3) Radar level gauge: It can work in harsh conditions and can measure almost all media. It can be measured including toxic, corrosive media, solid, liquid, dusty, and slurry media. The measurement is continuous and accurate, no maintenance is required, the feasibility is strong, the maintenance is convenient, and the operation is simple. Non-contact measurement, independent of temperature, pressure, gas, etc.
4) Magnetostrictive level gauge: It is a positioning product developed by the principle of magnetostriction. The output signal is an absolute value, which does not pose a problem for data reception, and does not need to re-adjust the zero position. The internal construction is non-contact and does not cause any wear on the sensor. The output is direct, no need to add an output interface. The output is accurate and reliable, the sensor is rugged and durable, and has a long life without regular maintenance or calibration.
5) Differential pressure level gauge | Level gauge: The height of the liquid level is reflected by the gauge pressure signal, which is easy to install, easy to realize remote transmission and automatic adjustment, and is widely used in industry. For relatively mature liquid level measuring instruments, the measurement accuracy is high, the maintenance amount is small, and maintenance is important;
6) Magnetic flap or magnetic flip column level gauge: the local display does not require power supply, the display part is completely isolated from the medium, and the observation will be affected by the media contamination of the display strip. The switch point position is adjusted according to the user's needs, and the bundled position is installed. The liquid level transmitter outputs 4~20mA signal for remote detection or control. The maintenance amount is small and the maintenance cost is low.
7) Servo level gauge: mainly used in high-precision measurement of light oil (non-corrosive liquid). The basic principle is the same as the steel belt type liquid level gauge. It has precise force sensor and servo system. It has high precision and can reach 1mm. It is more complicated to install and debug. The contact level gauge has high price.
8) Capacitive level gauge: It has extremely high anti-interference and reliability, and solves the influence of temperature, humidity, pressure and conductivity of materials on the measurement process. It can measure highly corrosive liquids such as acids, alkalis, salts, sewage, etc.
9) RF admittance level gauge: It is a new level control technology developed from capacitive type, anti-hanging material, more reliable, more accurate and more applicable. It is an upgrade of capacitive level technology.
10) Float level gauge: According to the buoyancy principle, when the liquid level rises, the column turns from white to red, and when it falls, it turns from red to white, thus achieving liquid level indication.
11) Steel strip level gauge: It is designed and manufactured by the principle of mechanical balance, with strong practicability, large measuring range, high precision and high performance, long service life and easy maintenance.
12) Static magnetic grid level gauge: direct output absolute liquid level data, long range, moderate resolution, no contact characteristics, can save absolute liquid level data for a long time after power failure. Impact resistance, water resistance, oil resistance, dust resistance, pollution resistance, no fear of foam, intuitive and accurate reading, multiple output signals, convenient connection with the existing control network of the workshop, easy maintenance and replacement, etc., making it a liquid level detection and control Required equipment.
