What is the difference between a flow meter and a rotameter?
A variable area flow meter (rotameter) is a flow meter that measures the volumetric flow of liquids and gases. There is no difference between a variable area flow meter, rotameter, or a flow meter, and these terms are interchangeable.
Structure and principle
BTLZ series intelligent metal tube float flowmeter consists of two
Part composition:
1. Sensor -- Measuring tube and float;
2. signal transmitter ---- indicator;
There are four kinds of liquid connection materials for the sensor: stainless steel and Hastelloy
Gold, titanium, stainless steel lining FEP; Users can vary according to
Process pressure and corrosive medium requirements, choose different contact liquid
Material to meet the needs of pressure resistance and media anticorrosion of the process. According to different measurement requirements, users can choose different types when selecting
Combination of indicators to achieve different measurement requirements. The specific indicator form and its corresponding function are shown in the indicator type chart.
The flow rate is measured by the transmitter in the indicator to sense the change of float position through the coupling magnetic steel to complete the flow indication and signal
Far out of the transmission. When the measured medium flows through the measuring tube from bottom to bottom, the float is affected by gravity, buoyancy and fluid velocity
When the three driving forces are balanced, the float is relatively stationary at a certain position, which changes with the annular gap area between the float and the cone and the fluid flow rate
The position of the float corresponds to the size of the measured medium flow

How to use (installation)
There are 12 steps required to install the sanitary metal tube rotameter.
1. Clean the welding slag and debris in the pipeline before installing the flow meter;
2. The installation inclination of the upright part of the calibration flowmeter perpendicular to the ground shall not exceed 5°. Otherwise, the measurement accuracy will be affected.
3. Position In order to ensure the measurement accuracy of the flow meter, a straight pipe section of no less than 10xDN should be added to the inlet end of the flow meter, and a straight pipe section of no less than 5xDN should be added to the outlet end. The regulating control valve should be installed at the flow meter during measurement. downstream.
4. Model If the measured medium is a large pulsating flow or two-phase flow, a buffer should be installed upstream of the flow meter to reduce or weaken the pulsation to ensure that the flow of the medium is single-phase stable. At the same time, it is recommended to use a damping type flow meter. .
5. Measuring medium When the measuring medium is dirty or contains magnetically conductive particles, it is recommended to install a filter or magnetic filter upstream of the flow meter.
6. The installation of the support flow meter should be able to properly support the vibration of the pipeline or reduce the axial load of the flow meter. Otherwise, the support of the fixed flow meter should be added.
7. Maintenance In order to facilitate the maintenance and repair of the flow meter, the cleaning of the magnetic filter and the regular maintenance of the user's pipelines, it is recommended to use the bypass pipeline as shown in the figure.
8. Stability When the flow meter is used for gas measurement, it should be ensured that the working pressure in the pipeline is not less than 5 times the pressure loss of the flow meter, so that the flow meter can operate stably and normally.
9. Before using the electric remote transmission and the flow meter with alarm limit switch, open the instrument cover and connect the wires correctly according to the wiring diagram.
10. According to the warning plate on the indicator of the meter, take out the damping piece that prevents the float from vibrating during transportation, and then use the meter after restoring it.
11. If the flow meter is turned on, because there is no pressure in the pipeline or the system has not reached the normal working pressure of the instrument, slowly open the control valve until the system is normal before the instrument can be used. Otherwise, it is easy to cause the pointer to jump or the float to suddenly move. A rose damaged by impact.
12. User use: When the user uses it, if the density of the measured fluid is different from that of water, or the parameters and working status of the measured gas are different from the manufacturer's regulations, the flow meter indication reading should be converted. The conversion method is shown in the appendix.
Precautions
Precautions when using the sanitary metal tube rotor flowmeter.
1. Metal rotor flowmeter, metal tube float flowmeter, and Verabar flowmeter with high temperature resistance up to 450°C.
2. Suitable for measuring small diameter and low flow rate gas, liquid and steam flow.
3. High-voltage resistant magnetic coupling principle, no leakage and high pressure resistance.
4. Measure the flow rate. When the flow rate exceeds 100m3/h water flow rate, the pressure loss will be large. .
5. The measuring range is mostly used for process control instruments, with an accuracy of 1%, usually 1.5%, and a range ratio of 10:1.
6. Suitable for occasions, including intrinsically safe explosion-proof and explosion-proof types, suitable for dangerous occasions.
7. Installation method The appropriate installation method is vertical installation with bottom in and top out.
