Overview
The GZC-1 oil storage tank intelligent comprehensive measurement and control system is suitable for the measurement of oil storage tanks, separation tanks, and settling tanks in the petroleum and chemical industries. It can accurately measure the liquid level of the medium in the oil storage tank, the position of the oil-water interface, and the tank at the same time. The thickness of the bottom sludge, the moisture content of each layer, temperature, inventory and other indicators. At the same time, it has an alarm function for important indicators.
The GZC-1 intelligent comprehensive measurement and control system for oil storage tanks has completely broken the measurement model of oil tanks in tank areas in the petrochemical industry, enabling it to truly realize the automation of comprehensive measurement of multiple indicators. Make full use of advanced technology, processes and materials to combine multiple sensors into a multi-functional sensor that can achieve the measurement of five indicators. Applying high-resolution stepper motors to oil tank measurement not only ensures the accuracy of measurement, but also improves the reliability of the equipment. The computer configuration design is reasonable, compatible with the HART protocol, and can monitor the entire measurement process in real time. The menu display is easy to operate; faults are self-diagnosed; and it is convenient for networking and connection. The explosion-proof design of this system breaks the single-type design model in terms of product performance. It is the only field instrument that adopts a repeated explosion-proof design, that is, double explosion-proof and intrinsically safe. It can effectively solve many problems in the production management process of the petrochemical industry, save energy and reduce consumption, greatly reduce the additional costs caused by intermediate links in crude oil production, eliminate environmental pollution caused by water discharge from oil tanks, improve the quality of exported crude oil, and has great social significance. meaning and economic significance.

working principle
1. The multi-functional sensor uses high-frequency short wave to measure the conductivity of the measured medium to measure the liquid level in the oil tank, the oil-water interface, the moisture content of each layer and the sludge at the bottom of the tank. The temperature measurement of the layer adopts digital temperature. sensor. Monolithic acquisition circuit and its peripheral circuits. Realize the collection and transmission of original signals.
2. The measurement actuator has built-in stepper motor, transmission mechanism, highly automatic calibration components, dual-channel safety energy limiter, single-chip acquisition circuit and its peripheral circuits. The high-resolution stepper motor provides power and drives the multi-function sensor to move up and down through the suspension rope (signal cable) to achieve accurate measurement of all heights; the height automatic calibration component automatically calibrates the height before each start of measurement, and then Measurement is carried out; the single-chip acquisition circuit and its peripheral circuits are responsible for receiving multi-function sensor signals, processing them and sending them to the industrial computer.
