Q: 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.

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.

Q: 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. Read more about: Hydrostatic Submersible Level Transmitter-Straight Rod Insertion

Q: 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.

Question 5

What is magnetostrictive transducer?

Accepted Answer

Magnetostrictive liquid level transmitter is a kind of liquid level sensor. But it uses the principle of magnetostrictive operation internally. And combines modern electronic technology to measure the time value between pulse waves to achieve the purpose of accurately measuring the liquid level . The magnetostrictive liquid level meter works with waveguide pulses. During the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse, so the measurement accuracy is high.

Question 6

How does a magnetostrictive sensor work?

Accepted Answer

1.The device electronics generates a low energy current pulse at fixed intervals.
2.The electrical pulses create a magnetic field which travels down a specialized wire inside the sensor tube.
3.The interaction of the magnetic field around the wire and the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire.
4.A patented sensing element placed in the transmitter assembly converts the received mechanical torsion into an electrical return pulse.
5.The microprocessor-based electronics measures the elapsed time between the start and return pulses (Time of Flight). And converts it into a position measure-ment which is proportional to the level of the float.

Question 7

How does a level indicator transmitter work?

Accepted Answer

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.

Question 8

What is radar level transmitter?

Accepted Answer

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.
