Hydrostatic Pressure Transmitter Working Principle
The hydrostatic pressure transmitter, also known as a hydrostatic liquid level gauge or hydrostatic pressure level transmitter, measures liquid level and hydrostatic pressure by leveraging the fundamental principle that the pressure at the bottom of a liquid column is directly proportional to its height and density.
This advanced hydrostatic pressure transmitter typically consists of a high-stability sensor or probe placed at the bottom of the tank or container. The sensor detects the hydrostatic pressure exerted by the liquid above it and converts this pressure into a precise electrical signal, usually a standard 4–20 mA DC output. This allows accurate, real-time liquid level readings for monitoring and control applications.
Key advantages of this measurement principle include:
High Accuracy: Provides precise liquid level measurement even in corrosive or challenging environments.
Reliability and Stability: Continuous monitoring with minimal drift, suitable for long-term industrial and environmental applications.
Integration: Can be easily connected with PLC, SCADA, or DCS systems for real-time process control.
Versatility: Compatible with water, oil, chemicals, and other liquids, making it ideal for industrial, thermal power, sewage treatment, and petroleum applications.
Hydrostatic Pressure Level Transmitter Structure
The hydrostatic pressure transmitter, also known as a hydrostatic liquid level gauge or hydrostatic pressure level transmitter, is engineered with a robust and reliable structure to ensure accurate and stable liquid level measurement across various industrial applications.
Key Structural Components:
Diaphragm/Sensor: The core component is a high-precision piezoresistive sensor with corrosion-resistant stainless steel or Hastelloy diaphragm. This sensor accurately detects the hydrostatic pressure of the liquid column and converts it into a stable electrical signal.
Probe: A submersible probe or sensor is placed at the bottom of the tank or container, ensuring continuous and precise monitoring of liquid levels.
Housing: The transmitter is housed in a durable, IP68-rated waterproof casing, making it suitable for submerged operation in tanks, reservoirs, and open water channels.
Cable & Connector: Shielded and corrosion-resistant cables transmit the signal to the control system. Connectors and process fittings, including G1/2, NPT, and flange types, are customizable for different installation requirements.
Electronics Module: Includes temperature compensation circuitry and signal processing units to ensure accurate 4–20 mA DC or other standard output signals under varying environmental conditions.
This modular design ensures easy maintenance, long-term reliability, and compatibility with PLC, SCADA, or DCS systems. The hydrostatic pressure transmitter’s structure is suitable for measuring water, oil, chemical liquids, and other media in petroleum, chemical, thermal power, sewage treatment, and industrial applications.
