How does A Magnetostrictive Sensor work?
- When the sensor of the magnetostrictive level transmitter works, the circuit part of the sensor will excite a pulse current on the waveguide wire.
- When this current propagates along the waveguide wire, a pulsed current magnetic field is generated around the waveguide wire.
- There is a float outside the sensor rod of the magnetostrictive liquid level gauge. This float can move up and down along the rod with the change of liquid level.
- Inside the float there is a set of permanent magnetic rings. When the pulsed current magnetic field and the magnetic ring magnetic field generated by the float want to meet. The magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the float.
- This pulse is transmitted back along the waveguide wire at a fixed speed and detected by the detection mechanism.
- The position of the float, that is, the position of the liquid surface can be accurately determined by measuring the time difference between the pulse current and the torsional wave.
More Level Senors for Tank Level Measurement
Tank level senor is a level sensor used to measure the tank level. The liquid level is the level of the liquid in a sealed container (such as a water tank) or an open container (water tank). The instrument that measures the liquid level is called a liquid level sensor, a liquid level gauge or a liquid level transmitter. The liquid level sensor is a kind of level instrument. Hydrostatic, Ultrasonic, Magnetostrictive, Radar, Differential Pressure are commonly choices for tank level measurement. Liquid level sensors have been around for decades for leak detection or level measurement. Common measured medium are: Water, Fuel, Diesel, Gasoline, diesel, liquefied gas, liquid ammonia, etc. More about Level Senors for Tank Level Measurement.
Radar level transmitter
Radar level transmitter, also called Radar level gauge. Non-contact Continuous level measurement in liquids and solids with free space radar sensors. Non-contacting radar, based on microwave technology, detects only surfaces that reflect energy. These transmitters work on the principle of a radar by using radio wave emissions. Mounted at the top of a tank filled with a liquid. The transmitter sends a radar signal into the liquid, and receives a reflection of the signal. The transmitters then analyze the current fill level of the tank based on the time taken by the transmitted signal to return.
GWR level transmitter
Guided Wave Radar (GWR) Level Transmitters, also called wave guided radar level transmitter. Using guided wave radar technology, GWR level transmittershave no moving parts. They can measure both level and the interface between two media. Continuous level measurement in liquids and solids with guided wave radar sensors. These transmitters work by sending a microwave pulse through a sensor cable or rod. The signal hits the surface of the liquid, and travels back to the sensor, and then to the transmitter housing. Based on the time taken by the signal to travel down the sensor and back up again. The electronics integrated in the transmitter housing determine the filling level.
Hydrostatic level transmitter
Hydrostatic level transmitters, also called submersible level transmitter, or pressure level transmitters. For Hydrostatic level measurement, Continuous level measurement in liquid applications with pressure sensors. These transmitters help in determining fluid level of a container. By measuring the pressure of resting body of the fluid within it.
Ultrasonic level transmitter
Ultrasonic Level Indicator, also called Ultrasonic level sensor, or ultrasonic level transmitter. In this type of transmitter, an ultrasonic transducer is mounted at, or near the top of a container containing liquid. The transducer sends out an ultrasonic pulse. The pulse hits the surface of the liquid, and gets reflected. The sensor then calculates the fill level based on the time between the transmitted and received signal.

Many people may confuse the float level sensor with the magnetostrictive level sensor. Because they look alike. But the actual working principle is different.
How does a level transmitter work?
The level of the liquid medium in the container is called the liquid level. And the instrument that measures the liquid level is called the liquid level transmitter. Level transmitter is a kind of level instrument. There are two types of level transmitterss, one is continuous and the other is point-off. The continuous level transmitter is a real-time monitor of the height of the liquid in the container. The point type, which generally takes two points, high and low, and outputs an alarm signal when the medium in the container reaches these two points.The types of liquid level transmitters is very wide. Specific include: magnetic flap liquid level gauge, tuning fork vibration type, differential pressure type, pressure type. Ultrasonic, magnetostrictive liquid level gauge, magnetic flap, radar and so on.
Levels of media such as: water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.
Level measurement transmitter are used in a myriad of applications that require level measurement within containers or tanks. These transmitters often find their application in material handling, food and beverage, power, chemical, and water treatment industries.
What is radar level transmitter?
Radar level transmitter is a kind of liquid level transmitter which uses the principle of radar operation.
Radar Level Sensor also called radar level transmitter, are the indicating transmitter for liquid level.
Non-contact Continuous level measurement in liquids and solids with free space radar sensors.
RADAR (Radio Detection And Ranging) is a device which can detect the presence of faraway objects by obtaining a reflection of electromagnetic waves emitted from the device itself. Although invented much earlier, wide deployment of radar was done by Britain during the Second World War to detect oncoming German bombers.
Radar level measurement is a safe solution. Even under extreme process conditions (pressure, temperature) and vapors. Various antenna versions for every kind of radar applications are available.
In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.
How does capacitance level measurement work?
Capacitive level sensor is a device that converts the change of the measured object position into capacitance. Capacitance level gauge has simple structure, high resolution, reliable operation and fast dynamic response. It can be measured non-contact, and can work under harsh conditions such as high temperature, radiation and strong vibration. It has been applied in various fields of industrial and agricultural production. But traditional capacitive level meters all use analog circuits. Because the dielectric constant of the measured medium changes. Stray capacitive interference. Temperature drift. Influence of scraping and other factors. The application range of the traditional capacitive liquid level gauge is limited.
