The Anhui Tiankang TK-YB Input Type Liquid Level Transmitter is designed for continuous liquid level measurement in tanks, wells, reservoirs, water treatment systems, and industrial storage vessels. It measures liquid level by detecting the hydrostatic pressure generated by the liquid column and converts the signal into a standard output for PLC, DCS, or local monitoring systems.
The TK-YB series can be supplied in different structures, including cable type submersible level transmitter, rod type level transmitter, and flange-mounted hydrostatic level transmitter. It is suitable for water, wastewater, chemical liquids, storage tanks, underground wells, reservoirs, and process vessels where stable liquid level measurement is required.
The Anhui Tiankang TK-YB input type liquid level transmitter is a hydrostatic level measurement instrument. It is installed from the top or side of a tank, pool, well, or vessel, and the sensing probe is placed into the liquid.
The transmitter measures the pressure generated by the liquid height. Since liquid pressure increases with depth, the transmitter can calculate the liquid level according to the measured pressure and liquid density.
This product is commonly used when non-contact level instruments such as ultrasonic or radar level transmitters are not suitable, or when the application requires a simple, stable, and cost-effective level measurement solution.
Typical installation forms include:
The TK-YB hydrostatic level transmitter works according to the pressure generated by a liquid column.
In simple terms:
Liquid Level → Hydrostatic Pressure → Sensing Probe → Signal Conversion → 4–20 mA / Level Output
The relationship is:
Pressure = Liquid Density × Gravity × Liquid Height
When the liquid level rises, the pressure at the sensor increases. When the level falls, the pressure decreases. The transmitter converts this pressure change into a proportional level signal.
For open tanks, wells, and reservoirs, this method is very practical. For closed pressurized tanks, a differential pressure level transmitter is usually more suitable because the top pressure of the vessel must be compensated.
The TK-YB measures liquid level through hydrostatic pressure. This principle is stable and widely used for open tanks, water tanks, wells, pools, reservoirs, and wastewater systems.
The cable type structure uses a probe connected with a special cable. The probe is lowered into the liquid, while the transmitter head or junction part remains above the tank or well.
This type is suitable for:
The cable material should be selected according to the medium. For clean water, standard cable material may be sufficient. For corrosive liquid, chemical-resistant cable or PTFE structure may be required.
The flange-mounted type is installed through a tank flange or vessel connection. This structure is more suitable for industrial tanks, process vessels, and storage tanks where a fixed mechanical connection is required.
Compared with cable-only installation, flange mounting provides:
For some applications, a rigid rod structure may be used instead of a flexible cable. This is useful when the installation depth is fixed and the probe must remain stable inside the tank.
Rod type structures are commonly used for:
The TK-YB can be used for many liquid level applications, including clean water, wastewater, industrial water, chemical liquids, storage liquids, and compatible process fluids.
For corrosive liquids, slurry, high-viscosity liquids, or liquids containing sediment, probe material and structure should be selected carefully.
The transmitter can be used with a local display head or connected to remote indicators, PLC, DCS, or monitoring systems. The display can show the liquid level or pressure-derived level value depending on configuration.
Depending on the site conditions, the wetted parts and probe structure can be selected in stainless steel, PTFE, or other corrosion-resistant materials.
For chemical tanks, wastewater systems, acidic or alkaline liquids, material compatibility must be confirmed before ordering.

The cable type submersible level transmitter is the most common input type level transmitter. The probe is directly submerged into the liquid, and the cable both supports the probe and transmits the signal.
It is suitable for:
This structure is flexible and easy to install, especially where no fixed flange connection is available.
The flange-mounted hydrostatic level transmitter is installed through a flange on the tank or vessel. The probe extends into the liquid, and the transmitter head is fixed above the flange.
It is suitable for:
For closed tanks or tanks with internal pressure, the application must be checked carefully. If the gas pressure above the liquid changes, a differential pressure level transmitter may be required instead.
The rod type level transmitter uses a rigid probe instead of a flexible cable. It is suitable for applications where the measuring depth is not very large and where the probe position must remain fixed.
It is often used for:
For corrosive liquids, the transmitter can be designed with anti-corrosion materials such as PTFE. This structure is suitable for acidic, alkaline, or chemically aggressive media where stainless steel may not be suitable.
Before selecting PTFE or other anti-corrosion materials, the exact medium, concentration, temperature, and pressure should be confirmed.
The TK-YB is widely used for water tank level monitoring in industrial plants, buildings, water supply systems, and utility systems.
The cable type structure is suitable for deep wells and groundwater monitoring. The probe can be lowered into the well, while the transmitter signal is transmitted to a display or control system.
Used in wastewater tanks, sewage pits, treatment pools, and sludge-related liquid level applications. For wastewater containing sediment or corrosive components, material and probe protection should be selected carefully.
Suitable for reservoirs, ponds, open pools, canals, and other open liquid level applications where hydrostatic measurement is practical.
With suitable wetted materials, the TK-YB can be used for chemical tank level measurement. For corrosive liquids, PTFE or other anti-corrosion structures may be required.
The flange-mounted type can be used for process vessels or storage tanks where a fixed flange connection is required.
Used in filtration systems, dosing tanks, clean water tanks, wastewater tanks, and environmental monitoring projects.
