Principle and installation of liquid density meter

Weigh the hydrometer before the densitometer. Conceptually, density has a similar physical meaning to specific gravity, which describes the amount of matter contained in a unit volume of an object. bSeTextile Testing Instruments, Testing Equipment Manufacturer


If the volume of an object is v, its mass is m, and the acceleration due to gravity is g (=0.98 m/s2), then the weight of that object is mg. bSeTextile Testing Instruments, Testing Equipment Manufacturer


At this time, the density of the object is m/v and the specific gravity is mg/v. Apparently the numerical difference between density and specific gravity is only one gravitational acceleration g. Earlier we used the concept of specific gravity, we just used the concept of density. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Since objects have three basic forms: solid, gas and liquid, there are corresponding types of density meters. Liquid density meters are used to measure the density of liquids. bSeTextile Testing Instruments, Testing Equipment Manufacturer


The liquid density meter uses the Prinzip of vibrating cylinder density sensor to test liquid density. After the liquid to be measured is pumped into the resonance cylinder sensor, the single-chip microcomputer takes over the measurement process, which is fast, direct and highly sensitive. bSeTextile Testing Instruments, Testing Equipment Manufacturer


This density meter can be widely used to measure the density of various liquids, and with different concentration conversion software, it can also directly read the concentration or specific gravity of the corresponding liquid. B. alcohol, through the processing of single-chip software, the volume concentration data can be read out directly, and the test is more convenient. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Important installation pointsbSeTextile Testing Instruments, Testing Equipment Manufacturer


The choice of installation environment:bSeTextile Testing Instruments, Testing Equipment Manufacturer


1. The liquid density meter should be in a place without direct sunlight, vibration, wind, dust and magnetic field interference. bSeTextile Testing Instruments, Testing Equipment Manufacturer


2. The ideal place to get upllen is a 20°C/68°F and 50% humidity environment. bSeTextile Testing Instruments, Testing Equipment Manufacturer


3. Make sure the voltage used matches the voltage required by the liquid density meter. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Level Adjustment: Use the leveling feet to align the air bubble on the Lianyungang color wheel with the center of the Lianyungang color wheel, so that the whole machine is in a horizontal state. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Test bench installation: Place the test bench in the center of the test board. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Installing the tank placement plate: Place the liquid placement plate in the two concave fixed grooves on the host. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Install the windshield and insert the liquid density meter into the windshield. bSeTextile Testing Instruments, Testing Equipment Manufacturer


How it worksbSeTextile Testing Instruments, Testing Equipment Manufacturer


It's like squeezing a tube filled with liquid with your fingers, and the liquid in the tube moves vforward as the fingers slide forward. The peristaltic pump is also based on the same principle, except that the fingers are replaced by rollers. bSeTextile Testing Instruments, Testing Equipment Manufacturer


Peristaltic pump features:bSeTextile Testing Instruments, Testing Equipment Manufacturer


No pollution: the liquid only touches the pump tube, not the pump bodybSeTextile Testing Instruments, Testing Equipment Manufacturer


High precision: repeatability, high stability and precisionbSeTextile Testing Instruments, Testing Equipment Manufacturer


Low shear force: an ideal tool for transporting shear-sensitive and aggressive liquidsbSeTextile Testing Instruments, Testing Equipment Manufacturer


Good sealing: good self-priming ability, can be empty Rotation prevents backflowbSeTextile Testing Instruments, Testing Equipment Manufacturer


Easy maintenance: no valves and sealsbSeTextile Testing Instruments, Testing Equipment Manufacturer


U-shaped surge tube methodbSeTextile Testing Instruments, Testing Equipment Manufacturer


The The square of the period of oscillation of the vibrating tube is proportional to the density of the liquid sample placed in the tube. The design principle of the U-shaped oscillating tube is based on this. bSeTextile Testing Instruments, Testing Equipment Manufacturer
