Question 1

remote water tank level sensor

Accepted Answer

Generally, we can monitor the liquid level of the water tank remotely. You can choose wired or wireless remote monitoring.

Wired remote transmission, generally the output signal of the liquid level sensor. Such as 4-20mA, RS485 and so on. Through the signal line, the liquid level information can be displayed remotely.

Wireless remote transmission, generally a liquid level sensor through a wireless signal. The use of LORA debugging method and NB-IoT communication method can greatly increase the communication distance. It can be widely used in the field of short-distance Internet of Things wireless communication in various occasions. Real-time monitoring of on-site liquid level data, alarm processing, statistical analysis and other functions.

The appropriate remote water tank level sensor can be configured according to the actual needs of users.

Question 2

electronic water level sensor

Accepted Answer

The principles of liquid level sensors may vary, and their applications vary widely. Electronic or mechanical, remote or on-site display, contact or non-contact, it's dizzying.

In addition to the way of connecting the measured container to visually display the liquid level, the mechanical liquid level gauge is used. Another way to measure is to use the buoyancy of the liquid surface. So that the buoy or float can follow the change of the liquid level, which is converted into the display of the liquid level. These two methods are simple though. But very stable and reliable.

The biggest feature of the mechanical level gauge compared to its electronic level gauge is that the internal structure is very simple and the counting is intuitive. A variety of materials are available, which can achieve anti-corrosion and explosion-proof, and can adapt to various installation environments.

Magnetic flap level gauge, glass tube level gauge, glass plate level gauge, float level gauge, etc. These are the most widely used mechanical liquid level display instruments on the market. They are widely used in petroleum, metallurgy, chemical, paper and other industries.

What about electronic? Generally speaking, the ones that need power supply are basically electronic. Float, capacitive, radar, ultrasonic, remote magnetic flap including liquid level transmitter and so on.

It's easy to tell them apart, whether it's powered internally or externally, whether it's 24V or 220V. In short, the electronic must be powered to work.

Unlike the mechanical type, the working principle of the electronic level gauge is varied. For example, the radar level gauge uses microwaves, the magnetostrictive level gauge uses current pulses, the static pressure type uses the pressure generated at the bottom of the measured medium, and the ultrasonic level gauge uses ultrasonic waves to measure the liquid level.

High precision, easy installation, and adaptability to various installation environments are the characteristics of electronic liquid level display instruments. Compared with the mechanical type, they have a higher level of technology, but at the same time, the price is much higher than the mechanical type.

Question 3

external water tank level indicator

Accepted Answer

External Tank Level Indicator refers to an externally mounted level sensor. It is used to install on the outside of the liquid storage tank to measure the liquid level of the tank. When measuring with External Tank Level Indicator, install the ultrasonic probe just below the outer wall (bottom) of the container under test. No need to cut holes, easy to install. Does not affect on-site production. It can realize accurate measurement of various toxic substances and various pure liquids in high temperature and high pressure airtight containers.

Question 4

How does a float water level sensor work?

Accepted Answer

The Float water level sensor uses a float to track the rise and fall of the water level, and directly drives the record in a mechanical way. The use of the float water level sensor requires logging equipment (including the water inlet pipe), which is suitable for the low sandy river section with stable bank slope and little river bed erosion. The float water level sensor is widely used in China.

Question 5

Water level float switch price

Accepted Answer

The price of the water level float switch is mainly determined by some parameters:
structure type;
Wetted material
Pressure Level;
Flange specifications
Explosion-proof type
temperature;
Measuring range;
Insertion length
Medium density
Other contents such as density, operating temperature, operating pressure, electrical interface, etc., must be specified in the specification so that we can use them as reference data when designing the output.

Question 6

How do you use a float switch in a water storage tank?

Accepted Answer

Water level float switch is generally used for high level water tank water supply and sewage tank drainage. The device that converts the water level signal into an electrical signal to control the start and stop of the pump is called a water (liquid) level controller. Common water (liquid) level controllers include:Reed switch water level controllers. Float magnetic switch liquid level controllers. Electrode type water level controllers. Pressure type water level controllers, etc.

Question 7

What is water level control?

Accepted Answer

Liquid level controller refers to the control of high and low liquid level by mechanical or electronic methods. It can control solenoid valves, water pumps, etc. to achieve semi-automatic or full automation. There are many methods, depending on the choice of different products different.

Question 8

How do you adjust a float switch?

Accepted Answer

Notes on installation and adjustment of float level switch:

The float level switch only needs to re-calibrate the water level line before we install it. The switch itself cannot be adjusted. At this time, use a multimeter to measure the switch state. It will be turned on and off with the water level near the water line, which means that there is no problem.

Just make sure that the water level line of the thermal equipment is consistent during the installation. For example, the liquid level switch of SOR is usually attached to the water level line on the wall of the cylinder. We soak the switch in the water tank and slowly sink to make the water surface gradually approach the marking line. When you get closest, you will hear the micro switch the sound of.

Note that:
High-temperature liquid level switches, etc. have high operating temperatures and high water temperatures. The density of hot water is lower than the density of room temperature water, so the action line of room temperature water is lower than the switch marking line. Low level alarm is connected to normally closed (NC), high level is connected to normally open (NO). This type of switch is not difficult to install. The liquid level switch itself will have more than two pairs of micro-switches, which respectively output two pairs of normally open and two pairs of normally closed contacts, which are usually "on alarm" when applied.

Question 9

How do you make an automatic water level controller?

Accepted Answer

Control the high and low water levels by mechanical or electronic methods. It can control solenoid valves, water pumps, etc. to become an automatic water level controller or a water level alarm, thereby realizing semi-automation or full automation.

Question 10

What is the difference between level switch and float switch?

Accepted Answer

Liquid level switch is a general term. There are many types of level switches. Such as ultrasonic liquid level switch, electrode liquid level switch, capacitive liquid level switch, etc. The float level switch is also one of them.

Question 11

What is the function of the float level switch?

Accepted Answer

The float level switch is a controller used to control the detection and control of the water level.

The float level switch is a liquid level control part with a simple structure and convenient use. It has no complicated circuits and will not be disturbed. As long as the material is selected correctly, any liquid, pressure and temperature can be used.
