Description

 The instrument can be real-time online measured the density for all liquids or fluid mixtures. In petrochemical industry, it can be widely used in oil, oil refinery, oil water interface measurement. In the food industry, it can be used in production sites for grape juice, tomato juice, fruit syrup, vegetable oils and the processing of soft drinks etc. even in the dairy industry, the paper industry. It can be tested by the black pulp, green pulp, white pulp and alkaline aqueous. It can also be applied in salt mining potash, potassium carbonate, natural gas, lubricant oil, biopharmaceutical etc.


Features


1.Using the unitized structure transducer with double-line, no moving parts and simple maintenance.
2.5 digit liquid crystal display (LCD) and backlight can be clearly showed in the dark.
3.Install and use conveniently, insert the liquid to display readings or use the external type.
4.Using the fluid or still fluid, it is suitable for the installation of pipes and tanks.
5.Can be online measured the liquid density continuously, no process interruption. Can be directly used in the production process control.
6.The all parts where touched the liquid are several kinds of medium that are made by stainless steel or special materials. Safety and health.
7.Health types can be installed in the field of food production.
8.The safety and explosion-proof types can be both selected. Can be used in dangerous.

Temperature Influence: zero point error is the maximum range 1%/55℃
Power Influence: <0.005%/V of output range.
Vibration Influence: In any direction of axis, frequency is 200Hz, the error is the maximum range ±0.05%/g.
Load Influence: only the pressure of input transducer is high to 12V, there is no loading effect in the working area of load. 
Installation Position Influence:  Because of themselves pressure medium, the position of installation will
make great impact. It can not be corrected by the way of zero, but no influence after correction.


Application


1.The principle of on-line densimeter is a kind of differential pressure method based on the double probe that can be measured accurately. So just make sure the double probe is fully immersed, then the static pressure is stable, even if it is stired constantly. It is suitable for equipment of testing density. If there are some bubbles that can influence the density, should be added some testing pots on the unsuitable for direct measurement.
2.The installation drawing will be decided by the technicians in work site according to the equipments sizes.
3.It should be added some testing pots when the flowing liquids or larger vibration liquids were tested, in order to reduce bubbles that can make the reading stability. The field operator adjust the flow of liquid in the testing pot that should be refered the two readings of dynamic and stability.
4.When install the density meters on site that must be make sure the two probes are vertical the ground, then can make measurement errors.
The density meters can be tested the concentration according to different mediums academically, please according to the site conditions to get the concentration results on its own.
