1、Product overview
SDT600-2A ONLINE DENSITOMETER/CONCENTRATION METER adopts the special law of Coriolis force acting on the liquid in motion, Coriolis force and density are closely related to each other, thus it can get density of the liquid. And the concentration value 20ºC is calculated based on the density and the temperature. The measurement based on this principle is stable and precise, without the sensor drift; In the petrochemical industry it can be widely used in oil refining, oil detection; In food industry, it can be used for sugar, vegetable oil and beverage processing production, also for weak acid solution measurement of paper making and chemical industry, wine, salt, printing and dyeing and other industries. It is especially suitable for the working conditions of unclean or high viscosity with the installation options of on the pipeline or on the side of the vessel.
2. Main features:
1) 4-wire transmitter with integrated structure, no moving parts and simple maintenance
2) 5 digits display for density value, four decimals(one for concentration), current and temperature display in real-time
3) parameters can be set in the menu
4) easy installation, displaying the values immediately after touching liquid
5) Applicable for fluids, applicable for installation on the pipes
6) There are temperature compensation, value fine-tune and calibration function by pure water.
7) Continuous online measurement of liquid concentration during non-interrupted process, can be directly used in the process control of production
8) All wetted parts are made of 316 stainless steel or PTFE, safe,
hygiene and anti-corrosive.
