ZW-LZB/ (S Series) Plastic tube rotameter The main part of the cone tube are composed of AS, ABS plastic, good corrosion resistance, has the characteristics of reasonable structure, small volume, light weight, cone tube is not easily broken, it brings great convenience to use. The products are widely used in chemical industry, environmental protection, food and other industrial sectors. The connection can be divided into: inserting, welding, threaded and flanged connections four.

Two, work principle:

ZW-LZB/ (S) series of plastic tube rotameter is mainly composed of a bottom enlarged glass tube and a cone with the fluid flow rate to move up and down a floater. 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.

The float position meter readings as shown in Figure 2:

(ZW-LZB) S meter cone tube smooth inner wall of the tube (see Figure 4), the diameter of more than DN15 float flowmeter, stable movement, through the guide rod; (ZW-LZJ-) S flowmeter has three guiding cone tube inner ribs, the float remained stable (see Figure 4). 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/ (S) series of plastic tube rotameter is mainly used for corrosive liquid and gas medium flow detection, such as acid, 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. 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 is simple, the installation is very convenient, can be installed in a short period of time.

4, cheap. The price is very cheap, the price advantage.

Five, 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 bolt etc..

Six, installation instructions:

1, before installation, the foam support instrument within the tool pliers gently remove it, and then re install it, at the time of installation, should pay attention to the rubber gasket is mounted in the nozzle groove, to prevent Water Leakage.

2, flow interface, available supporting ABS or PVC plastic pipe, plastic pipe, bonding with special glue, is also connected by plastic method, and metal flange connection.

3, flow meter must be installed vertically, there should be no obvious inclination, the mounting height should be easy to float on the reading, reading, sight and float level should be. The general standard: the need for ideal flow meter Zui high flow 50%-70%, try not to use Zui high. .

4, the instrument on the lower reaches of the import and export shall ensure that there are 5 times the diameter of straight pipe instrument.

5, by side fluid pressure must be stable, such as fluid force too unstable, will cause the float fluctuation cannot be measured correctly, flowmeter should set the buffer or setting device.

6, plastic tube rotameter should be installed vertically, the angle between the line and the plumb line flowmeter center should not exceed 5 degrees.

Seven, matters needing attention:

1, the instrument used, should slowly open the valve to open the upstream and downstream of the flowmeter, flow regulating valve. The instrument stop should be used to slowly close the upstream valve, then close the meter downstream flow regulating valve.

2, the instrument indication in line to see, according to the height of the float rises at the present value of float gauge reading.

3, when the cone tube and float dirt, should be cleaned.

Error 4, regular check meter, once beyond the prescribed error, should replace the float and cone tube, or re calibration to get better precision.

5, the measured fluid and flowmeter calibration medium is uniform, the need for showing the value according to the revised. Represented by the formula QS=QN = Qn = QS actual flow flowmeter showing the value of P n = flowmeter calibration medium density s = density of measured medium f = float material density.

Eight, specifications and measuring range:

Twelve, the selection of encoding:

Eleven, ordering:

1, according to the measurement of the fluid is a gas or liquid, the correct selection of ZW-LZB rotor flowmeter.

2, the measured fluid is non corrosive with ordinary type, corrosive resistant type selection.

3, please specify when ordering the names, the measured flow rate, pipe diameter and pressure, temperature, density, viscosity, etc.. According to the user's density of correction, making special flow gauge.

4, according to the measurement range and measured fluid applications such as choosing the suitable type of the specifications. As the special requirements of the flowmeter, or call the sales department, and company.
