Tank level indicator float type

Float level sensor (float switch) is one type continuous level sensor for industrial level measurement. Float level sensor has a magnetic float that rises and falls as liquid level changes. The movement of the float creates a magnetic field. Through the magnetic coupling effect, the internal resistance of the sensor changes linearly. The resistance change is converted into a standard current signal of 4 ~ 20mA by an intelligent converter. The percentage of the liquid level, 4 ~ 20mA current and liquid level value, can be displayed on site. Applications like: water tank, fuel tank, level measurement and level control. Vertical, horizontal, and side mounted, all can be satisfied

Large water tank level indicator

The water level sensor of your water tank is an essential component. If not repaired or replaced, a sensor can become damaged over time and fail entirely. Too much water can cause a malfunction and too little water means inadequate water pressure. Either way, repairing or replacing holding tanks is an expensive task you shouldn’t have to undertake because of sub-par sensors.
With Sino-Inst’s water tank level sensors, there’s nothing to break down or rust and our models have a 99% success rate!

In the high unlikely event that you experience any issues with your product, call us and we’ll replace or repair it immediately at no charge.

Propane tank level indicator

Propane, three-carbon alkane, chemical formula is C3H8, structural formula is CH3CH2CH3. Colorless, liquefied gas is slightly soluble in water, soluble in ethanol and ether Mixed with air to form explosive mixture. Exist in natural gas and petroleum pyrolysis gas. The chemical properties are stable, and chemical reactions are not easy to occur. Used as refrigerant, internal combustion engine fuel or organic synthetic raw materials.

A propane gauge shouldn’t be hard to pick, and it shouldn’t cost a lot of money. We know that, so we’re going to show you how to pick the best propane tank gauges.

See if there is stirring in the tank. If there is a mixer, then add a measuring tube on the side of the tank. Generally, the magnetic flap level gauge, float level gauge or magnetostrictive level gauge are commonly used.

It also depends on your working conditions, such as temperature and pressure to measure the density of the medium, and whether your spherical tank is supported.

The external measuring liquid level gauge is also called an externally attached ultrasonic liquid level gauge. Its working principle is ultrasonic echo ranging. That is, the ultrasonic wave is transmitted through the tank wall in the liquid medium and returned to the liquid level to be received by the sensor. Through its time difference To calculate the liquid level height, on-site OLED display.

At the same time realize the remote transmission of the monitoring liquid level and realize automatic control. Also suitable for liquid level measurement of liquefied gas, propylene, propane, ethane spherical tank.

What is magnetostrictive level transmitter?

Magnetostriction means that the change of the magnetization direction in ferromagnetic substance will cause the change of the medium lattice spacing. As a result, the length and volume of the ferromagnetic substance change.
Magnetostrictive level transmitter is a level transmitter based on the principle of magnetostriction. It is a high-precision, high-resolution transmitter driven by a magnetic float.

How does a magnetostrictive sensor work?

1. When the sensor of the magnetostrictive level transmitter works, the circuit part of the sensor will excite a pulse current on the waveguide wire.
2. When this current propagates along the waveguide wire, a pulsed current magnetic field is generated around the waveguide wire.
3. 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.
4. 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.
5. This pulse is transmitted back along the waveguide wire at a fixed speed and detected by the detection mechanism.
6. 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.

What is flow and level sensor?

1. Flow sensor is a kind of detection instrument used to detect the flow parameters of liquid, gas and other media and convert it to other forms of signals for output. The flow sensor has many advantages such as small size, light weight, intuitive and clear reading, high reliability, and no pressure loss.
1. Level sensor is a sensor that can replace manual measurement. The liquid level sensor can convert the height of the liquid level into an electrical signal for output, so as to achieve the purpose of controlling the liquid level.
