Glass tube rotameter

Productoverview:

ZW-LZB/LZJ series Glass tube rotameter According to its purpose and scope can be divided into: ordinary type, ribbed vascular type, small flow and low profile type, corrosion type, laboratory type, insulation type, alarm type and high pressure type eight series. According to the formulation of national instrument series, regardless of which Zui series, ranging from 1 to 100 mm in diameter and a total of 12 numbers, can measure the flow range: liquid (water) 0.1 ml / min to 40 cubic meters / hour, gas (air) 1 ml / min to 1000 cubic meters / hour. For environmental protection equipment of the glass rotameter is generally not more than 10 mm diameter, the flow measurement of small flow range.

Two, work principle:

ZW-LZB/LZJ series of glass tube rotameter is mainly composed of a bottom enlarged glass tube and a cone with the magnitude of fluid flow moves up and down the stainless steel float. The fluid flows through the cone bottom tube, buoyancy A fluid kinetic energy generated on the float lift S and fluid to float up, when the lift and buoyancy of A and S is equal to the gravity float G, float in the balance, stable at a certain height position, cone scale on the tube indicates that the fluid flow value.

ZW-LZB- (F) for smooth wall cone tube flowmeter tube diameter meter above DN15, the float remained stable through the movement, the guide rod; ZW-LZJ- (F) three meter cone tube guide rib, the float remained stable. Through the meter diameter of DN10 or less connected by a hose, equipped with needle flow control valve; path DN15 flowmeter with flange connection.

Three, application:

ZW-LZB/LZJ series of glass tube rotameter is mainly used in chemical, petroleum, light industry, medicine, chemical fertilizer, chemical, food, dyestuff, environmental protection and scientific research departments, used to measure single-phase non pulsating (liquid or gas) fluid flow.

Anticorrosion type is mainly used for the detection of corrosive liquid and gas medium flow, such as acid and alkali, oxidant, strong oxidizing acid, organic solvents and other corrosive gas or liquid medium flow detection.

Four, main features:

1, small pressure loss. In the process of using, can be fully utilized, without a lot of effort too much, all the pressure can be fully used, there will be no loss.

2, reliable performance. Glass rotor flowmeter in operation, frequent failure will not ensure good operation. When people are in the process of using, don't worry about running for it. Good performance, high reliability, can be assured use.

3, simple structure, convenient installation and use. The structure of the glass rotameter is simple, the installation is very convenient, can be installed in a short period of time.

Fifth, technical parameters:

1, size: DN2 ~ 100mm;

2, measuring range: water (20 C): 1L/h ~ 100m3/h, gas (101325Pa, 20 C): 16L/h ~ 3000m3/h;

3, the range ratio: 10: 1;

4, precision grade: grade 1.5, grade 2.5, grade 4;

5, nominal pressure: DN4 ~ 10 1.0MPa, 50 0.6MPa, DN15 ~ DN80 ~ 100 0.4MPa;

6, working temperature: less than or equal to 120 DEG c;

7, connection: hose, metal pipe, flange (GB/T9119-2000);

8, material: flange, float, a guide rod, a supporting plate and bolts are made of stainless steel 304 (1Cr18Ni9Ti), type LZB-B.

Note: the wetted materials for use in 316, is a model for the LZB-Bo, can be customized.

For stainless steel PTFE is type LZB-BF (or BoF), can be customized.

Six, selection method:

1, measurement. Measuring the media type, size, pressure and chemical properties. Such as liquid and gas medium, the corrosive medium should choose corrosion resistance meter.

2, the performance of flowmeter. The above conditions are identified in general, if the price is no big change, may be preferred needle valve is arranged on the upper part of the large circulation flow meter; hole, direct flow scale; simple structure; small exterior dimensions etc.. Such as small flow range, you can choose to use the ball float type, because of its measurement stability, not easy dust, high precision, good interchangeability.

The price of 3, according to the. Generally speaking, the high price of high precision. According to the measurement instruments such as precision grade, only through the medium of control measure, the operation adjustment, after always stabilize the throughput, so the accuracy is minor.

Seven, matters needing attention:

1, don't put the front cover removed, because the glass tube easy blasting, shell to protect.

2, when used in winter, should pay attention to keep warm, if the night is not used, the residual liquid in the flow discharged, so as not to freeze broken glass tube.

3, to the pipeline installation, first look at the downstream pipeline is in a straight line. If not in a straight line, will not only affect the measuring accuracy of the instrument, but also will damage the flowmeter.

4, when the valve is opened, will slowly open, if the estimated flow to floating rotor, and the rotor does not move up, immediately stop valve, tap the pipeline, so that the rotor can slowly rise.

5, first observed within the flow tube is intact, glass tube is easy to damage; second is to remove the rotor fixture, gently slide backward to see whether the rotor freely up and down. If not free to slide, vibration plate gently. If we can not slide, would need professional solutions.
