A Capacitance level transmitter is an electronic device that measures the level of liquids, slurries, or solids by detecting changes in electrical capacitance between a probe and the tank wall. As the material level rises, it acts as a dielectric, altering the capacitance, which is converted into a continuous output signal .

Key Aspects and Features:

·Working Principle: The probe serves as one plate of a capacitor, and the tank wall (or a reference probe) acts as the other. A rise in material changes the dielectric constant, increasing the capacitance, which is detected via Radio Frequency (RF) signals

·Applications: Ideal for measuring conductive and non-conductive liquids, slurries, and solids, even in high-temperature or high-pressure environments.

·Advantages: They are highly reliable, durable, and can be used for interface detection between two immiscible liquids.

·Limitations: Buildup on the probe can cause inaccuracies, requiring calibration to handle coating or material changes.

·Probes: Available as rigid rods for shorter tanks or flexible cables for tanks up to 15 meters deep.

Petrotech SWNR1000A Series Radar Level Transmitter is high-frequency level measuring instruments with the maximum measuring distance up to 70 meters. The antenna is further optimized, and the new Type microprocessor can perform higher rate of signal analysis and processing, making the Instrument available for complex measurement conditions, such as reactors, solid silos.

 WORKING PRINCIPLE

The microwave comes into contact with the measured medium surface then reflected back and receiving by the antenna system. The signal is transmitted to electronic circuit and partly convert to level signals (as the microwave featured with high propagation speed, it's almost instantaneous for the electromagnetic waves to reach the target and return to the receiver)

PETROTECH Differential Pressure (DP) type level transmitters are widely used in industrial applications to measure liquid levels in both open and closed vessels by calculating the hydrostatic pressure exerted by the liquid column.

Working Principle

The transmitter measures the difference between high-side pressure  and low-side pressure

Open Tank: The low-side port is vented to the atmosphere, and the high-side port is connected to the bottom of the tank. The transmitter measures the hydrostatic pressure of the liquid, which is proportional to the level.

Closed Tank: The high-side port is connected to the bottom (wet leg), and the low-side port is connected to the top of the tank (dry or wet leg) to compensate for vessel pressure.
