一、Product introduction

WS3051MD—T6 Side mounted type gas protection density meter is mainly rely on the scene to promote the use of gas sources, also known as the air protection act integrated online density meter; That is the latest development of our company and patented products, innovative products, technology leadership, quality assurance, import assembly. Integrated products, safe and reliable. 

Side mounted type gas protection density meter is mainly used to exposure, or in low pressure and seal the tank liquid density measurement precision, especially in the sewage, and easy scaling, strong corrosive, strong acid and alkali, temperature, explosion, viscosity and so on bad situations. Is the general of a measurement method, not only is safe and reliable, mature measurement principle, and it overcomes the shortcomings of other density measuring instrument, without any mechanical drive and displacement in the process of measurement, and high precision, simple construction without flare, do not need to tank.

WS3051MD—T6 Side mounted type gas protection density meter in the explosion-proof area,airtight pot measurement of liquid density system from the following aspects. The trachea: more than or equal to Φ 36mm PTFE pipe and other pipes, then indeed liquid, its length is less than or equal to 2 meters. Installation is complete, check no leakage, density meter is connected to the power, throttle valve open to all pass state. Then the compressed gas continuously into the densitometer connected port until full of air tightness meter converter flatus. Inflatable after 3 minutes, due to the size of the gas pressure in the air pressure converter is determined by the liquid level in the tank, so to stop the exhaust is tank liquid level height of the formation of the pressure equal to static pressure converter and pipeline of air pressure, density transmitter of the analyzer is detected, differential pressure and the height of the liquid level in the tank (storage density) numerical. Therefore, the change of the density of the actual liquid in the storage tank can be achieved, which can achieve the purpose of detection. According to the principle that the pressure is equal everywhere in the sealed pressure vessel, the same is equal to the inside of the pipeline and the pressure converter.

二、Operational principle

WS3051MD—T6 Side mounted type gas protection density meter essentially for high precision differential pressure transmitter, by gas blowing two fixed gas detection medium density; its working principle: liquid column pressure and the fixed height is proportional to the density of liquid.


        In the formula: P——liquid column pressure and the fixed height

                             ρ——the density of liquid

                             h——height of liquid column

According to the pressure measuring pressure value in measuring acceleration of gravity with known height of liquid column under the condition, can be measured liquid density.

五、 Installation requirements

Due to the need for the process, the side mounted type gas protection density meter is often installed in the relatively poor working conditions of the site, as far as possible in order to reduce the density meter working conditions deteriorated, should try to install in small changes in temperature gradient and temperature, no shock and vibration of the place, no air bubbles.Only considering the specific conditions of the site, to make the accuracy index. Pay attention to the following items when installing:

The product must be installed vertically and vertical to the ground not more than 5 degrees (such as not installed vertically, or the local acceleration of gravity deviates from the standard acceleration of gravity, will result in bias, the following will introduce how to eliminate the  resulting deviation.

The side of the installation must ensure that the level of direction.

After opening the cover of the electric box, the reinstallation should be tightened to ensure close contact with the sealed O type ring, If not tightened, the moisture will enter the  electrical box, the impact of the normal operation of the circuit.

The density meter of the shell must be effectively grounded.

The installation position as far away from the inverter or high power motor, when necessary to take isolation measures, the use of shielded power cable.

After installation, empty tube or empty tank, then zero calibration, the density value is displayed as 0g/cm3.
