Details
Q1: What is a submersible level transmitter?
A1: A submersible level transmitter is a liquid level measurement device designed to be immersed directly into a tank, well, reservoir, or other liquid environment. It measures liquid level by detecting hydrostatic pressure and converts the pressure signal into an electrical output, such as 4-20mA or RS485, for monitoring and control systems.
Q2: How does a submersible level transmitter work?
A2: A submersible level transmitter works based on hydrostatic pressure measurement. As the liquid level increases, the pressure at the bottom of the liquid column also increases. The transmitter measures this pressure change and converts it into a proportional electrical signal that represents the liquid level.
Q3: How to choose the right submersible level transmitter?
A3: When selecting a submersible level transmitter, consider factors such as measuring range, cable length, output signal, accuracy, liquid type, and installation conditions. Models with 4-20mA output are commonly used in industrial control systems, while RS485 versions are suitable for digital communication and remote monitoring applications.
Tips: What is the measuring range of the submersible level transmitter?
The SISCO Submersible Level Transmitter supports measuring ranges from 0–1 m to 0–200 m, making it suitable for different liquid level measurement applications, including deep wells,
reservoirs, water tanks, dams, and industrial liquid storage. The 0–200 m range is designed for deep-level monitoring and can provide continuous and reliable liquid level measurement.
