1. Overview of magnetostrictive level gauge

It can measure the liquid level and boundary level of various storage tanks or process tanks; it is an intelligent field instrument that can achieve trade-level high-precision liquid level (interface) measurement;

It can be inserted in the top of the tank and used alone;

It can be used with the magnetic flap and installed on the side of the tank;

The purpose of measuring liquid level and interface can be achieved by increasing the number of floats;

You can directly measure the interface by selecting a suitable float;

Second, the advantages of magnetostrictive level gauge

This product is a German original product, and its high quality and high cost performance make it widely used in various liquid level measurement.

Advanced SYSTEC technology

(1) Measurement accuracy: ±1.0mm (2) Resolution: 1.0mm (3) Boundary level and liquid level can be measured at the same time (4) Built-in temperature compensation (5) 2-wire system (4~ 20mA) (6) "HART" protocol (optional) (7) fast response speed, very short sampling period (8) widely used in explosion-proof occasions (ATEX, IECEx certification) (9) simple structure, robust design, long life and high reliability (10) Shock and vibration resistance (11) The measuring range can be adjusted arbitrarily in the length of the probe, and the calibration is simple. (12) The installation is simple, no need to adjust and modify the parameters, and it can run after power on

Third, the structure of the magnetostrictive level gauge

1. Transmitter meter head part: stainless steel meter head, capable of separate liquid level indication, two-wire output (power supply/communication), HART communication (optional)

2. Sensing part: including piezomagnetic sensor and long-life magnetostrictive signal pulse waveguide

3. Magnetic float part: There are many models for different density, pressure and material. The material can be 316Ti, pure titanium or Hastelloy.

4. Typical application of magnetostrictive level gauge

1. Liquid level monitoring in petrochemical process

2. Oil-water separation interface measurement

3. Oil tank farm

4. Gas station

5. Chemical production and storage

6. Introduction to the working principle of magnetostrictive level gauge

Magnetostrictive level gauges mainly use the physical properties of magnetostriction for measurement, and are not affected by changes in dielectric constant, temperature or pressure of the medium. There is a tensioned magnetostrictive wire inside the non-magnetic sensor tube

(1) The circuit unit emits current pulses along the magnetostrictive line;

(2) A toroidal magnetic field is generated around the magnetostrictive wire;

(3) There is a set of permanent magnets in the liquid level float or the boundary level float;

(4) Their own magnetic field magnetizes the magnetostrictive wires in the axial direction. When the current magnetic field and the magnet magnetic field are superimposed, the magnetostrictive wire at the position of the float will generate an instantaneous torsion;

(5) At the same time, a return pulse is generated, and the pulse is transmitted to both ends along the magnetostrictive line, one end is transmitted to the top of the sensing tube, and the other end is transmitted to the bottom of the sensing tube. The pulse wave returning to the top will be received by the transmitter electronic unit. Since the propagation speed of the pulse wave is a constant value, the electronic unit can calculate the position of the magnetic steel in the float only by the time difference between the initial pulse and the return pulse, thereby obtaining the most accurate liquid level and boundary level.
