Types of Level Transmitters
Liquid Level Transmitters detect levels of liquids. Liquid level transmitters also detect interfaces between liquids such as oil and water. You will find liquid-level transmitters in storage, transport, and water storage tanks. These transmitters measure the level by measuring the head pressure of the liquid.
Ultrasonic transducers mounted at or near the top of a container use an ultrasonic pulse. The pulse hits the surface of the liquid and reflects. The sensor then calculates the fill level based on the time between the transmitted and received signal.
The principle of capacitive level measurement is based on a change in capacitance. An insulated electrode acts as one capacitor plate, and the tank wall acts as the other plate. The capacitance depends on the fluid level. An empty tank has a lower capacitance, while a filled tank has a higher capacitance.
By measuring the variations in capacitance, the transmitters calculate the fill level of the tank.
A hydrostatic level sensor measures the hydrostatic pressure in a liquid at a pre-determined depth. Hydrostatic level sensors measure fluid levels by the pressure of the resting body of the fluid within the vessel. The greater the force of liquid, the greater the volume of fluid.
These transmitters use a magnetic object suspended in a buoyant float. This transmitter is suitable for continuous measurement due to the rise and sink of the float based on the liquid level. Utilizing a combination of proven buoyancy principles with the benefits of magnetism, magnetic-level transmitters can fit almost any process.
These transmitters work on the principle of radar based on electromagnetic waves at a range of 10GHz under microwave X-band bandwidth. 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 transmitter then analyzes the current fill level of the tank based on the time the transmitted signal takes to return.
Small containers are often controlled with just a Level Switch, but for medium-sized and large containers, instead of installing multiple Level Switches at the top, middle, and bottom, a Level Transmitter is used to continuously measure the storage level and calculate approximate storage level in real time.
It is often displayed and used.
In some cases, Level Transmitter is also used to check the intermediate storage amount while controlling with a Level Switch.
This also has the advantage of making it easier to notice if there is a problem with a certain sensor.
Since it can be detected early, it can reduce impact on production process and prevent stress on equipment.

How to Calibrate a Level Transmitter
Before using a level transmitter, it needs to be calibrated. This process involves setting the output signal of the device so that it accurately reads the actual fluid level. The calibration procedure will vary depending on the type of level transmitter being used.
Submersibles, for example, should be set up in such a way that they are sitting at least 6 inches below the surface of the liquid they are measuring. The output signal should be adjusted so that it reflects the actual fluid level. Pressure transducers, on the other hand, should have their sensitivity adjusted so that it is consistent with the desired range of measurement. Hammer unions require adjustments for inline pressure to ensure proper readings. Lastly, digital pressure gauges must be calibrated using a calibration device.
With proper calibration, a level transmitter can provide accurate information about fluid levels in open or closed tanks. This data can be used to make sure that processes are working properly and that materials are being handled safely.

What are the Precautions for Level Gauge
Precision function check
Accuracy level and function According to the measurement requirements and application occasions, select the instrument accuracy level to achieve economical and cost-effective. For example, for trade settlement, product transfer and energy measurement, you should choose a higher accuracy level, such as 1.0, 0.5, or higher; for process control, choose different accuracy levels according to control requirements; some only It is the occasion to check the process flow without precise control and measurement. You can choose the lower accuracy level, such as 1.5, 2.5, or even 4.0. At this time, you can choose a low-cost plug-in level gauge.
Measurable medium
Measuring medium flow rate, instrument range and caliber When measuring general medium, the full-scale flow of the liquid level gauge can be selected within the range of measuring medium flow rate 0.5-12m/s, and the range is relatively wide. The specifications (caliber) of the selected instrument are not necessarily the same as the process pipeline. It should be determined according to whether the measurement flow range is within the flow rate range, that is, when the pipeline flow rate is too low to meet the requirements of the flow meter or the measurement accuracy cannot be guaranteed at this flow rate, Need to reduce the diameter of the instrument, so as to increase the flow velocity in the tube, and get satisfactory measurement results.
Troubleshooting
Routine inspection of liquid level gauge and troubleshooting method, suitable for magnetic flap liquid level gauge, two-color quartz tube liquid level gauge, glass tube liquid level gauge, etc.
First check whether the power supply is connected correctly. If you find that the connection is incorrect, you should modify it according to the operation manual.
Use a three-voltmeter to measure the voltage between +24V and O/P. The voltage should be between 13V and 36V. If the voltage is abnormal, check whether the circuit or related equipment is abnormal.
Item 2 should be confirmed to be normal first, and then connect a milliampere meter in the 4~20MA circuit to check whether the current is normal. If the current value is abnormal, replace it with a new product or contact customer service staff.
Check the voltage between IN and COM with a voltmeter. The normal voltage should be about 2.5V. If the voltage is too low, the EXC wire should be removed. If the voltage returns to normal, it means that the magnetic yellow module is abnormal. If the power is still low It means the signal converter is damaged. If you find the above phenomenon, you should replace the signal converter according to the actual situation or contact customer service personnel.
Note on the Use of Liquid Level Transmitter
Select the regulated power supply separately. The stability of the power supply affects the performance of the transmitter, and its error is controlled to less than one-fifth of the allowable error of the transmitter. For products with special power requirements, special power supplies must be adopted.
The liquid level transmitter signal line should adopt a shielded cable to prevent electromagnetic interference.
Connect the transmitter according to the correct wiring method. The power-on time should be 15 to 30 minutes.
If the liquid level transmitter is installed in a pool, water tower, etc., it can sink its probe to the bottom of the water, away from the position where the water flow rate is too fast.
In the case of a liquid level transmitter ULB6 used in large fluctuations such as submersible pumps, the method of inserting the steel pipe is adopted. The steel pipe should be fixed firmly and a hole should be opened at every interval on the steel pipe. The position of the steel pipe should be far away from the inlet and outlet.
The junction box should be fixed firmly, or install a fixed bracket to put into dry, shaded places and can not be rained.
Protect the ventilation cable. It should not be bent or blocked, and it should not be damaged. The extra cable can be folded up nearby.
The outdoor installation of the liquid level transmitter should also take lightning protection measures.
