Propane tank level indicator is also called propane tank gauge level indicator, or propane tank level gauge. What kind of level gauge is used for Industrial propane level measurement?
Propane is a gas that can be liquefied. Chemical formula CHURCH, colorless, liquefiable gas. Slightly soluble in water, soluble in ethanol and ether.
Common Industrial Propane Tank Level Indicators for Industrial Tank Level Measurement include radar level sensor; magnetostrictive level sensor; float level gauge; magnetic flap level gauge; ultrasonic level gauge.
Sino-Inst offers a variety of Level Transmitters for level measurement. If you have any questions, please contact our sales engineers.

How to Measure Propane Tank Level
Radar level transmitters use radar technology to perform a non-contact continuous level measurement. The radar level indicator converts the level into an electrical signal. The level signal output can then be utilized by other instrumentation to monitor or control. Liquids and solids are commonly measured with this measuring technique. Like: Fly ash silo. Radar level sensors are divided into Pulsed radar technology and frequency modulated continuous wave (FMCW) radar level sensors.
Sino-Inst produces 120GHz FMCW radar level sensor, 26GHz radar level meter, 6GHz level meter.

⑴ The working principle of the magnetic level gauge is based on Archimedes’ law.
Using the principle that the weight of the float is equal to the weight of the volume of the liquid discharged by the float, the float-equipped with magnetic steel changes with the change of the liquid level.
The position of the magnetic line of force in the float (that is, the actual liquid level position) drives the turning column and the turning plate through magnetic action. When the liquid level rises, the liquid phase turns red.
When the liquid level drops, the gas phase turns white or black. So as to clearly indicate the change of the liquid level in the container.
⑵ A ruler is installed on the display panel so that the liquid level can be read directly. A valve is installed at the lower end of the body for sampling and draining.
The most significant feature of the Magnetic propane tank level indicator is that the liquid medium is completely isolated from the indicator. So it is very safe and durable under any circumstances. Moreover, various types of liquid level gauges are equipped with liquid level alarm and control switches, which can realize the upper and lower limit offside alarm control or interlocking of the liquid level or boundary level.
Equipped with a dry reed chipset liquid level transmitter, it can convert liquid level and boundary signals into two-wire 4-20mADC standard signals. It is transmitted to the computer, regulator, and liquid level indicator to realize remote indication, detection, recording, and control.
Magnetic level gauges are widely used for liquid level measurement and control in various production processes such as petroleum, chemical, metallurgy, pharmaceutical, food, and electric power.

Float level sensors are continuous level sensors. Float level gauges use magnetic floats as measuring elements. magnetic float that rises and falls as liquid levels change. The movement of the float will generate a magnetic field. The sensor’s internal resistance changes linearly, and the intelligent converter converts the resistance change into a 4~20mA standard current signal. It can display the liquid level percentage, 4~20mA current, and liquid level value on the spot. It can also output the switching value signal to conduct liquid Bit switch control. Float level sensors are low-cost liquid level measurement and control instruments.
You can choose single-point or multi-point measurement and control. Can bring huge profit difference for OEM. float level sensors can be used for liquid layer measurement. Such as oil/water tanks, liquid material inventory, and measurement in high temperature, high pressure, and corrosive environments.

Magnetostrictive Level Transmitters are used for continuous measurement of liquid level and interface. Magnetostrictive level measurement is currently the best liquid level measurement and control technology.Sino-Inst’s Magnetostrictive Level Transmitters can provide two independent outputs: interface; overall level. It can be applied when the difference in specific gravity drops to 0.02.
Magnetostrictive Level Sensors Commonly used for the measurement of the oil-water interface. And others include acid tanks, propane containers, desalter and sewage tanks.
Magnetostrictive Level Transmitters are composed of three parts: probe rod, circuit unit and magnetic float. The flexible cable type and the outer buoy type are derived from the basic model. And has a variety of communication modes 4~20mA, 0~5V, 0~10V, HART, RS-485 and so on.

The external measurement type level gauge is also called the externally attached ultrasonic level gauge. Its working principle is ultrasonic echo ranging, that is, ultrasonic waves are transmitted through the tank wall and then conducted in the liquid medium, and the liquid surface returns to the bottom to be received by the sensor. The height of the liquid level is calculated by the time difference. On-site OLED display, while realizing remote transmission of monitoring liquid level, realizing automatic control.
Field of application of external level gauge:
- The level gauge has a wide range of applications. In particular, the application of liquid level measurement for flammable, explosive, highly corrosive, toxic and harmful pressure vessel storage tanks is more prominent;
- Oil refinery: liquefied gas, propylene, propane, ethane spherical tank / horizontal tank level gauge
- Chlor-alkali industry: liquid chlorine storage tank level gauge
- Synthetic ammonia device: liquid ammonia spherical tank/horizontal tank level gauge
- Silicone industry: spherical tank/horizontal tank level gauges such as silicon trichloride, silicon tetrachloride, trichlorosilane, etc.
- Refrigeration industry: liquid ammonia, dichloroethane, hydrogen fluoride and other storage tank level gauges
- Level gauge applications in other chemical fields.
