4-20mA Ultrosonic Level Difference Gauge

The one - piece four - wire ultrasonic level gauge is a state - of - the - art instrument designed for highly accurate level measurement in a wide range of applications. Unlike the two - wire counterparts, this model features four wires for enhanced functionality. Two wires are dedicated to providing a stable power supply, typically DC24V or AC220V, ensuring reliable operation even in power - fluctuating environments. The other two wires are used for signal transmission, which can be either an analog 4 - 20mA signal for easy integration with standard industrial control systems or a digital signal such as RS - 485 for more complex data communication requirements.

In water treatment plants, the TSL300CJ plays a crucial role in monitoring the level difference between different treatment tanks. For example, it can measure the level difference between the inlet and outlet of sedimentation tanks, which helps in optimizing the water flow rate and ensuring the effectiveness of the sedimentation process. This, in turn, improves the quality of treated water.

In the petrochemical industry, it is used to monitor the level difference in storage tanks. By accurately measuring the level difference, operators can better manage the transfer of fluids between tanks, preventing over - filling or under - filling, and enhancing the safety and efficiency of the production process.

In power generation facilities, the gauge is used to measure the level difference in cooling water systems. Precise level difference measurement enables the efficient operation of cooling towers and heat exchangers, improving the overall energy efficiency of the power plant.

Environmental Applications

In wastewater treatment plants, the TSL300CJ is used to monitor the level difference in lift stations. It helps in controlling the operation of pumps, ensuring that wastewater is effectively pumped from lower - level collection points to higher - level treatment units. This ensures the smooth operation of the wastewater treatment process and prevents sewage backups.

In environmental monitoring of rivers and lakes, the gauge can be used to measure the water level difference between different sections. This data is valuable for flood prediction, water resource management, and understanding the flow characteristics of water bodies.
