The two-color water level gauge is widely used for liquid level monitoring in pressure vessels and industrial steam boilers. It provides a clear visual indication of the water and steam levels, making it an essential component in many industrial applications.
Common issues with two-color water level gauges include:
(1) Mismatch between the center distance of the steam and water valves on the gauge and the corresponding outlet pipes on the drum.
(2) Incompatibility between the operating pressure of the boiler and the rated pressure of the water level gauge.
The principle behind the two-color water level gauge is based on the use of prisms that utilize light transmission and reflection. This allows the water and steam to appear in different colors—typically green for water and red for steam—making the interface between them highly visible and easy to read. Unlike traditional glass gauges, the two-color version ensures that the colors do not mix under normal operation. However, improper installation or usage can lead to malfunction.
To ensure proper performance, the following steps should be followed during installation:
(1) Before installation, inspect all components for blockages or leaks.
(2) Verify that the center distance between the steam and water valves matches the spacing of the drum’s steam and water outlets.
(3) Ensure the selected gauge's working pressure matches the boiler's rated pressure. For example, a 1.6 MPa gauge is suitable for pressures below 1.3 MPa, while a 2.5 MPa gauge works well in the range of 1.3–2.0 MPa.
(4) After unpacking, store the gauge separately to avoid damage.
(5) During installation, clean the gauge thoroughly, avoid excessive force, and apply bolts evenly to prevent misalignment.

Hydraulic Cylinder
The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or oscillating motion). It has a simple structure and works reliably. When it is used to realize reciprocating motion, the deceleration device can be dispensed with, and there is no transmission clearance, and the movement is stable, so it is widely used in the hydraulic system of various machinery. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between its two sides, and the hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
