Conductivity level equipment is used to measure the level of a liquid in a tank or container by detecting its electrical conductivity. This type of equipment is particularly effective for liquids that conduct electricity, such as water-based solutions, acids, and bases. The basic principle of operation involves using electrodes that are immersed in the liquid. These electrodes are connected to an electrical circuit. When the liquid level reaches the electrodes, it completes the circuit, allowing current to flow. The presence or absence of current flow is used to determine the liquid level. There are typically two types of conductivity level sensors: point level sensors and continuous level sensors. Point level sensors detect whether the liquid has reached a specific level, often used for high or low-level alarms. Continuous level sensors provide ongoing measurement of the liquid level, offering more detailed monitoring. The equipment usually consists of a probe with multiple electrodes, a power supply, and a signal processing unit. The probe is inserted into the tank, and the electrodes are positioned at different heights. As the liquid level changes, different electrodes are submerged, altering the electrical path and allowing the system to determine the level. Conductivity level equipment is advantageous due to its simplicity, reliability, and low maintenance requirements. It is widely used in industries such as water treatment, chemical processing, and food and beverage production. However, it is not suitable for non-conductive liquids like oils or hydrocarbons. Additionally, factors such as temperature, pressure, and the presence of coatings or deposits on the electrodes can affect accuracy and performance.

Conductivity level probes detect liquid levels by utilizing the electrical conductivity properties of the liquid. These probes consist of one or more electrodes that are inserted into the tank or container where the liquid level needs to be measured. The basic principle involves completing an electrical circuit through the liquid. When the liquid level rises and makes contact with the probe, the circuit is completed because the liquid acts as a conductor. This completion of the circuit allows a small electrical current to flow between the electrodes. The presence or absence of this current is used to determine whether the liquid has reached a certain level. Typically, a conductivity level probe system includes a control unit that sends a low-voltage signal to the probe. The control unit monitors the circuit's status: if the circuit is closed (indicating the presence of liquid), the control unit registers this as the liquid reaching the probe's level. If the circuit remains open, it indicates that the liquid has not yet reached the probe. Conductivity level probes are particularly effective for detecting the presence of conductive liquids, such as water or aqueous solutions. They are less effective for non-conductive liquids like oils or hydrocarbons unless additives are used to increase conductivity. These probes can be configured for point level detection, where they indicate whether the liquid is above or below a specific point, or for continuous level measurement by using multiple probes at different heights. Conductivity level probes are widely used in various industries, including water treatment, chemical processing, and food and beverage production, due to their simplicity, reliability, and cost-effectiveness.
