At present, various types of domestic and foreignSubmersible Level TransmitterDifferent functions come with different prices. Some imported input-type liquid level gauges often cost hundreds of thousands of yuan, and the purchase cycle is long and accessories are scarce. Once a fault occurs, maintenance is quite difficult and installation is inconvenient. We are a manufacturer of input-type liquid level gauges. The price is right and it fully meets the actual needs of production. It is very convenient to install, debug and maintain. Choosing our input level gauge not only reduces production costs, but also saves a lot of money.

For the installation of the submersible liquid level meter, you only need to put the detection element of the submersible liquid level meter into the tank through the ruler hole of the large tank, and then use a clamp to fix the transmitter on the top of the tank. When put into operation, only a few zero and span adjustments are required. In order to improve the measurement accuracy and prevent impurities in crude oil from clogging the detection components, the submersible level gauge is placed at a safe tank position 2.5 m away from the bottom of the tank during installation, which effectively ensures the normal operation of the submersible level gauge.

The submersible level gauge uses a high-tech laser-engraved silicon diaphragm sensor. After sensing the static pressure of the liquid medium being measured, it will be converted into a voltage signal of 0-100mv, and then transmitted to the signal conversion circuit through a shielded cable. The external power supply can generate a reference voltage for the amplifier and conversion circuit through the internal reference power circuit, making it unaffected by changes in the external power supply. In order to meet the requirements of different sensors, this circuit is equipped with a high-precision constant current source or constant voltage source to power the sensor. This ensures high accuracy, and then outputs a current or voltage signal corresponding to the measurement range through a high input impedance amplifier and a high load capacity V/I converter. The input-type liquid level meter conversion circuit is designed using an integrated chip and has the following characteristics:

(1) Although the temperature compensation of the sensor is realized in a wide range (0-70), a temperature compensation circuit is added to the design of the signal conversion circuit, which eliminates the impact of circuit temperature drift on the measurement, reducing the impact of ambient temperature by 0.05 for every 10 degrees, and the temperature impact index of the entire liquid level transmitter reaches 0.1% for every 10 degrees;

(2) Power supply fluctuations have little effect on signal output. The power supply fluctuates in the range 12-38 V with an error less than half the basic error;

(3) The load capacity is very high, up to 1.5 times;

(4) It has great flexibility and can provide various signal output modes such as 4-2 0 rnA, 0-10 mA, 0-2 0 mA, 1-5 V, 0-5 V, etc. according to user needs.

The liquid level signal detected by the input liquid level meter is transmitted to the control room through the signal cable, and the actual liquid level changes can be observed on the CRT or display.

The performance of this input-type liquid level gauge is stable and reliable, its accuracy fully meets the requirements for tank level monitoring, and it is very convenient to install and maintain. Compared with the float level gauge, it has the advantages of less investment and easy maintenance. At the same time, by transmitting the liquid level variable signal to the computer, the liquid level changes can be easily observed from the CRT, which makes up for the lack of liquid level variables in the data acquisition system.
