Measuring Range 0–0.6 MPa to 0–40 MPa (customizable based on tank depth and medium density) Dial Diameter 100 mm (4 inches) Capillary Length 1.0 m, 1.5 m, 2.0 m, 3.0 m (custom lengths available) Connection Type Flange-mounted (DN25, DN40, DN50, or as specified)
This product is a pressure-type level indicator designed to measure liquid levels in tanks and vessels without requiring an external power supply. It operates by transmitting the pressure exerted by the liquid column in the tank through a diaphragm seal and a capillary tube filled with a heat-transfer fluid (typically silicone oil) to the indicating gauge. The gauge then converts this pressure reading into a corresponding liquid level or volume display on the dial.
