Installation Method
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 are the advantages of a digital submersible level transmitter?
A digital submersible level transmitter offers clear real-time level readings through its LCD display, allowing users to monitor liquid levels and configure parameters on-site with ease. Combined with a 1–10 m measuring range, IP65 / IP67 waterproof protection, and a corrosion-resistant stainless steel probe, it provides high accuracy, long-term stability, and dependable performance in both clean water and wastewater applications.
