Corrosion proof glass tube rotameter

Productoverview:

ZW-LZB/ (F Series) Corrosion proof glass tube rotameter 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. Corrosion proof glass rotameter is mainly used for the detection of corrosive liquid and gas medium flow, such as acid (except hydrofluoric acid), alkali, oxidant, strong oxidizing acid, organic solvents and other corrosive gas or liquid medium flow detection.

Two, work principle:

ZW-LZB/ (F) series of anti-corrosion glass tube rotameter, the main measurement components for a vertical installation of small large tapered glass tube, and the float can move up and down. When the fluid from top to bottom through a conical glass tube, the float between the upper and lower pressure difference, the rise in pressure under the action of the float. Buoyancy and viscous lift and float when the rising force, float by gravity is equal, the float is in balance position. Therefore, the fluid flow and float through the glass rotameter height is between the glass rotameter flow meters there is a certain ratio, the float position height can be used as a measure of flow.

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.

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

According to the rotor flowmeter its use 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 series, ranging from 1 to 100 mm 12 mm diameter, can measure the flow range: liquid (water) 0.1 ml / min ~ 40 / cubic meters, gas (air) 1 ml / min / m3 ~ 1000.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 rotor flow meter, 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, a case can not directly use its scale: one is not measuring medium of water and air, the second 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, selection guide:

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.
