Magnetostrictive level sensor
Magnetostrictive level sensor can measure oil level, water level and temperature at the same time.
High accuracy(+/- 1mm), Multifunctional and long life, it is the first choice for automatic detection of liquid level in oil tanks at gas stations and oil depots.
Measuring range
Our magnetostrictive level sensor has the measuring range of 0.3 meters to 25 meters.
If the length of the magnetostrictive sensor is 0.3m to 4m, you can choose our rigid magnetostrictive level sensor.
If the magnetostrictive sensor length exceeds 4 meters, you can choose the flexible magnetostrictive level sensor.

Magnetostrictive level transmitter Working principle
The magnetostrictive level sensor is designed based on the principle of magnetostriction.
Detection principle:
Send an “inquiry” pulse in each detection cycle,
The pulse is sent down from the top of the waveguide line,
Physical expansion and contraction (twisting force) occurs at the magnetization point of the waveguide line,
An echo is formed, which propagates upward along the waveguide line.
The time from sending the “inquiry” pulse to receiving the “return” wave is an accurate detection of the length.
Application
Magnetostrictive level transmitter are used for liquid level measurement and control of various liquid tanks such as petroleum, chemical raw material storage, industrial processes, biochemistry, medicine, food and beverage, tank farm management, and underground storage of gas stations.
Advantages of using magnetostrictive level sensor to measure oil tank level:
1. Strong reliability:
Since the magnetostrictive level sensor adopts the waveguide principle.
There are no mechanical moving parts, so there is no friction and no wear.
The entire transducer is enclosed in a stainless steel tube and is non-contact with the measuring medium.
The magnetostrictive sensor works reliably and has a long life.
2. High accuracy:
Since the magnetostrictive level sensor works with waveguide pulses, the measurement accuracy is high, and the resolution is better than 0.1mm, which is an accuracy that is difficult to achieve with other types of sensors.
3. Good safety:
The magnetostrictive liquid level sensor has high explosion-proof performance, intrinsically safe explosion-proof, and safe to use.
Especially suitable for the measurement of chemical raw materials and flammable liquids.
There is no need to open the tank lid during measurement, to avoid the insecurity of manual measurement.
4. Easy to install and simple to maintain:
Magnetostrictive level sensor are generally installed through the existing mounting holes on the top of the tank.
Especially suitable for the installation of underground storage tanks and operating storage tanks,
And it does not affect normal production during the installation process.
5. Facilitate system automation:
The magnetostrictive level gauge adopts the standard output signal,
It is convenient for the computer to process the signal, easy to realize networking work, and improve the automation degree of the entire measurement system.
Signal output:
RS485 Modbus
4-20mA

Flexible magnetostrictive level sensor Installation
1. Straighten the magnetostrictive sensor
First, straighten the flexible magnetostrictive level sensor on the top of the tank to prevent bending.
2. Component assembly
The installation sequence is to put the lock nut, adjusting nut, sealing rubber ring, flange, oil float, water float, and weight drop on the flexible magnetostrictive sensor in sequence on the top of the tank, and finally fix the tail, and the flexible magnetostrictive level sensor assembly is completed.
3. Degaussing operation
Demagnetize the flexible magnetostrictive level sensor before installation,
Move the oil float from the bottom of the flexible magnetostrictive level sensor to the top,
Then move the oil float from the top of the flexible magnetostrictive sensor to the bottom.
This completes the degaussing operation.
4. Hoisting
Put the flexible magnetostrictive level sensor’s weight drop and floats into the tank from the mounting hole.
5. Fixed flange
6. Adjust the length
The weight drop touches the bottom of the tank,
Put the rubber ring into the groove of the mounting flange and tighten the adjusting nut,
And fix it with a lock nut, and then fix the lock nut in place.
7.Install the protective cover

Gas station / Petrol station
XT-200 magnetostrictive probe widely installed in petrol stations, Skid-mounted station.
Magnetostrictive level sensor can accurately measure the fuel level, water level and temperature of tank, and transmit data real time.
It consists of floater kits, measuring rod and 316L protection tube, probe head and communication cable.
Magnetostrictive level sensor installation in Gas Station
1.The location of the installation hole should be far away from the equipment that is easy to impact such as the submersible pump
2.The diameter of the mounting hole should be greater than 80mm, and the best diameter recommended by the gas station is 100mm (DN100)
3.If the horizontal oil tank cannot be welded with a special mounting hole, the original DN100 manual oil measuring hole can be used.
Magnetostrictive level sensor wiring and installation:
1. Use RVVP4×0.5 shielded cable, the cable length is not more than 1200m.
2. No joints are allowed in the cable, and the entire cable must be used to connect to the explosion-proof junction box.
Each oil tank requires a separate communication cable,
For example, 4 oil tanks require 4 communication cables to be routed to the control room.
3. Cables must be installed with G1/2″ (4 inches) galvanized steel pipes in hazardous areas;
there should be G1/2″ threads at the explosion-proof junction box.
Leave a steel pipe with a length of 100mm and a G1/2″ thread at the wall of the manhole.
4. The shielding wire of the cable is grounded in the explosion-proof box, and the grounding resistance should not be greater than 10Ω.
5. The connection on site must be waterproof.
