Advantages of Magnetostrictive Level Gauge
High precision
The magnetostrictive liquid level gauge uses waveguide pulse to work. During the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse. Therefore, its measurement accuracy is high. The resolution is better than 0.01% FS. This is an accuracy that is difficult to achieve with other sensors.
Good safety
The magnetostrictive liquid level gauge has high explosion-proof performance. Safer to use. Especially suitable for the measurement of chemical raw materials and flammable liquids. It is not necessary to open the tank lid during measurement. There is no insecurity for manual measurement.
Strong reliability
Because the magnetostrictive liquid level gauge uses the waveguide principle. There are no mechanically movable parts. So there is no friction and no wear. The entire converter is enclosed in a stainless steel tube and does not contact the measuring medium. The sensor works more reliably and has a longer life.
Facilitate system automation
The secondary instrument of the magnetostrictive liquid level gauge adopts standard output signal. Help the computer to process the signal. It is easy to work on the Internet. Improve the automation of the entire measurement system.
Components of Magnetostrictive Level Gauge
Waveguide tube
Located inside the outer tube, composed of magnetostrictive material, is the core part of the level meter, responsible for transmitting magnetic field and strain pulses;
Float
Built-in permanent magnet, moves up and down with the change of liquid level. When the magnetic field of the permanent magnet in the float intersects with the magnetic field of the interrogation pulse on the waveguide, a strain pulse is generated;
Electronic unit
Generates a low-current interrogation pulse and receives the returned strain pulse. By measuring the time interval between the interrogation pulse and the return pulse, the liquid level value is accurately calculated.
Calibration Procedure
Verify to determine if the magnetostrictive level transmitter connections are stable.
Verify that the magnetostrictive level transmitter terminal has a 24 VDC power supply.
You will be able to verify a few of the parameters with the help of the data sheet that is included with the magnetostrictive level transmitter. Examples of usual parameters are the tag number, PV, LRV, and URV.
You may use a hart communicator to verify the parameters if it's a smart magnetostrictive level transmitter.
By using a standard measuring tape, the calibration points for the reference level from the data sheet should be marked on the gauge chamber of the magnetostrictive level transmitter.
In the case there's a calibration point marking, the same should be verified using a standard measuring tape.
A certain type of magnetostrictive level transmitter often comes with an external level scale mark on the exterior of the gauge chamber.
To drain the fluid from the chamber, close the top and bottom isolation valves connected to the magnetostrictive level transmitter's gauge chamber and open the drain valve.
The drain valve should now be closed, and the chamber of a magnetostrictive level transmitter gauge should be manually filled with process fluid through the bottom isolation valve until it reaches the 0% percentage mark on the chamber.
You should now look at the multimeter, which should be showing a 4mA output from the magnetostrictive level transmitter.
Locate the zero adjustment option on the magnetostrictive level transmitter display and make the appropriate changes there until the reading reads 4mA. Alternatively, you may utilize the HART Communicator to make the adjustments for smart magnetostrictive level transmitter.
The bottom isolation valve of a magnetostrictive level transmitter gauge should be opened to manually fill the chamber with process fluid until the chamber reads 100%.
Now check the multimeter; it should display a 20mA output from the magnetostrictive level transmitter.
On the magnetostrictive level transmitter display, find the span adjustment option, and make the necessary adjustments there until the readout reads 20 mA.
When filling the gauge chamber with fluid, you must ensure that the magnetic float moves very smoothly and that the output of the transmitter is increasing gradually in accordance.
If it is not possible to establish the level in the gauge chamber using the process fluid, then move the magnetic float to the desired calibration point.
Make sure that the mounting clamps for the magnetostrictive level transmitter sensor are secure and tight before making any adjustments.
You can move the transmitter sensor using sensor mounting clamps if you have linear error in the zero and span calibration points.
Repeat the calibration procedure for the magnetostrictive level transmitter as much as required until it is calibrated to the necessary tolerance.
The calibration process might need to be modified depending on the magnetostrictive level transmitter that is being installed in the process. Therefore, before beginning, please read the manufacturer's instructions for the magnetic level transmitter.
