Precautions for Installation and Use of Single Flange Level Transmitter The 3351GP single flange liquid level transmitter is widely used in metallurgy, chemical industry, environmental protection, power station due to its convenient installation, simple layout, convenient adjustment, high precision and good stability. Continuous monitoring of liquid level, material level, oil-water interface and foam interface in papermaking, pharmaceutical, printing and dyeing, food, municipal and other occupations.
Pay attention to the following points when using the HL3351GP single-flange liquid level transmitter:
â—When the single-flange liquid level transmitter freezes in the winter, the transmitter installed outside must adopt the anti-freezing method to prevent the liquid in the pressure-inducing port from expanding due to the icing volume, leading to damage to the sensor.
◠Temperature scale ambient temperature: -20 ~ +70 ° C; storage temperature: -20 ~ +80.
◠Power supply: Load resistance 0-750Ω DC24V.
â— When measuring the pressure of the gas, the pressure port should be opened at the top of the process pipe, and the flange level transmitter should also be installed in the upper part of the process pipe to allow the accumulated liquid to be quickly written into the process pipe.
â— When the single flange liquid level transmitter measures the liquid pressure, the pressure tap should be opened beside the process pipe to prevent deposition of slag.
â— Measurement scale pressure: 0 ~ 10Kpa ~ 7Mpa; Negative pressure: -100KPa ~ 7MP.

â…¡ Product Properties
The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolyticstability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.
III. Quality indicators;
Appearance: colorless to faint yellow thick liquid Solid content: 40±1%
PH value: 4.0~7.0 viscosity (mpa.s, 25℃): 7000-12000
IV. Application:
This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
