Level Transmitters, also called level gauges. Level transmitters are instrument that provide contact and non-contact level measurement. Level transmitter consists of sensor and eletrical transmitter. For continuous level measurement and point level detection in liquids and bulk solids. Levels in liquids, pastes, bulk solids or liquefied gases are often measured in tanks, silos or movable containers. Level transmitters have: magnetostrictive, radar, guide wave, ultrasonic, DP, and Hydrostatic types. Differential pressure transmitter with the capillary and diaphragm is a more economical choice. And magnetostrictive level transmitter is often used to measure the level of oil (diesel, fuel). If you have any questions about product selection, please feel free to contact us. We provide free technical guidance.
What is a Level Transmitter?
A Level Transmitter is sensor and eletrical transmitter, that provides continuous level measurement. Level transmitters can be used to determine the level of a given liquid or bulk-solid at any given time. This is different to a level switch which only alarms when the level of material (liquid or bulk-solid) reaches a predetermined level. Capacitive, radar, submersible, and ultrasonic are the different types available of level transmitters.
Level measurement transmitters are used in a myriad of applications that require level measurement within containers or tanks. 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.
How many types of level transmitters are there?
There are 7 main types of level transmitters that Sino-Instrument offers. Each type of transmitter works in a different way, and makes it useful for different types of processes.
Types of Level Transmitters:
Magnetostrictive level transmitter,in-tank liquid level transmitter, is a continuous magnetic level gauge. The magnetostrictive level sensor, measure the level of fluid in the vessel. By detecting the level of the magnets contained within the float and then transmits the measurement back to the control system.
Magnetic Float level sensors are continuous level sensors featuring a magnetic float that rises and falls as liquid levels change. The movement of the float creates a magnetic field that actuates a hermetically sealed reed switch located in the stem of the level sensor, triggering the switch to open or close.
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.
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.
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.
Guided Wave Radar (GWR) Level Transmitters, also called wave guided radar level transmitter. Using guided wave radar technology, GWR level transmitters have 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.
Differential Pressure (DP) Level Measurement uses pressure readings and specific gravity to output level. DP Level is a common measurement technique that is used in a wide variety of applications. Solutions include standard transmitter connections and integrated transmitters with direct or remote mount seals that can be configured in tuned, balanced, and electronic systems. Additional Wireless options are also available.
Capacitance level detectors, also known as Capacitance level transmitter. RF Capacitance Level Transmitter offers continuous and point level detection. In liquids and solids with capacitance probes. These transmitters use liquid stored in a tank or container as a dielectric medium between two or more electrodes. The energy capacity of the capacitor circuit increases when there is more liquid, and decreases if there is less liquid. Measuring the variations in the capacitance value, capacitance level transmitters calculate level of the tank.
