Description:

Productoverview:

ZW-LZB/ (W Series) Sanitary type glass tube rotameter With the scale and the transparent glass tube, can directly observe the instruction type flowmeter measured medium flow state. Suitable for measuring single-phase non pulsating fluid flow of liquid. From the measured parts in contact with the medium (except glass tubes) were produced by 0Cr18Ni9 or 0Cr17Ni12Mo2 materials, strong corrosion resistance, acid and alkali, can detect liquid oxidants and other corrosive flow, and equipped with sanitary quick clamp joint in the flowmeter, convenient installation and maintenance.

Second, working principle:

(ZW-LZB/) W series sanitary type glass tube rotameter measuring part is made up of vertically mounted plough and cone glass tube in the tube can be moved up and down a floater. When has a certain kinetic energy measured medium flows through tubes of glass cone plough, the measured medium buoyancy will have the geometry of the float float, float flow line reading position corresponding to the plow cone on a glass tube I want to cooperate, can read this time through the instantaneous flow of fluid in a pipeline, with the change of fluid kinetic energy. The float position, are constantly changing, but also changes in the value of the corresponding read.

Three, 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.

4, cheap. Buy glass rotameter is cheap, has a great price advantage.

Four, 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.

Wetted materials for the 316, is the model for the LZB-Bo, can be customized.

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

Five, installation instructions:

How to choose the right flowmeter is instantaneous flow measurement instrument using a simple and convenient reading, a very wide range of uses. In the field of environmental protection equipment in the amount of up to instrument 30000 Taiwan / year. Therefore, choose and use this instrument is very important.

1, variety and selection

Glass rotor flowmeter 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.

2, correction

The scale of the glass rotameter, is a production plant with a nearly ideal fluid in the factory under the condition of water and dry air as the medium for the calibration. But in the meter the use of the site, there are two kinds of situations can not directly use its scale: one is not measuring medium of water and air, two is measured and the medium is water and air, but the condition (temperature. Pressure) is different from the scale of state. So, in the use of flow time, to get the correct measurement results, there need to revise the scale value problem. Therefore, to solve the glass rotameter scale correction, is the key to good use of this instrument.

Considering the environmental protection equipment used by mining gas rotameter medium flow in great quantities, so just below the gas medium when measuring the density correction is discussed. Because the gas medium viscosity is very small, so the effects of omitting discussion viscosity. Practice has proved that this does not affect the accuracy of the revised.

Six, the selection of attention:

1, measurement. Measuring the media type, size, pressure and chemical properties. Such as liquid and gas medium, the corrosive medium should choose corrosion resistant glass rotor flowmeter.

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.

4, the fluid flows through the cone bottom-up 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, scale cone tube on the fluid flow indicator value.
