Overview

Electric contact Water Level Gauge measuring cylinder is mainly used for water level monitoring of various boiler bubbles, high and low pressure heaters, deaerators, evaporators and water tanks. This device is used in conjunction with the secondary instrument (FDZ electric contact liquid level indicator). It is designed based on the analysis of the characteristics of similar domestic products. Compared with similar products, it has a long life, less maintenance and a wide range of uses. and other advantages.
The Electrical Contact Water Level Gauge can be combined with the two-color Quartz tube type Water Level Gauge (ie, the double-connected two-color Electrical Contact Water Level Gauge, model: SFDZ-XX) to achieve the dual functions of on-site observation and long-distance monitoring.
Electric contact Water Level Gauge is divided into ordinary type (FDZ-XX) and self-compensating
There are two types of compensation type (ZB-FDZ-XX).

Structural principles and working principles

The Electrical Contact Water Level Gauge measuring cylinder is mainly composed of a sampling cylinder and an ultra-pure ceramic electrode, and is used in conjunction with a display instrument (FDZ Electrical Contact liquid level indicator).
The Electrical Contact Water Level Gauge measuring cylinder uses the boiler bubble water level as a signal. It utilizes the different impedances of ultra-pure ceramic electrodes in water and steam to output electrical signals with the help of electronic circuits. The water level and level are simulated through the LED of the FDZ Electrical Contact liquid level indicator. Digital display of water level enables long-distance water level monitoring. It also has the functions of sound and light high and low warning water level alarm and limit water level alarm output.
The self-compensating electric contact Water Level Gauge adds heat tracing and condensation devices to the ordinary type. The use of these two devices enables the water level in the Water Level Gauge to be kept consistent with the steam whether in the cold or hot state. The water level in the package is basically the same, making the Electrical Contact water level meter measurement true and accurate, with fast dynamic response, small additional error, and long electrode life. The differential pressure water level meter can also be checked in all working conditions, and the water level protection can be put into use when the boiler is started.
