GL30-25F glass rotor flowmeter with all stainless steel threaded connection

GL30-25F glass rotor flowmeter with all stainless steel threaded connection

Changzhou Liangbang Instrument Co., Ltd. is a professional manufacturer of flow and level instruments such as glass rotor flow meters, metal tube float flow meters, turbine flow meters, vortex street flow meters, and magnetic flap level meters. Our company has production processes and technical personnel. This product is a flowmeter for heat treatment furnaces. Our company's flowmeter is widely used in large-scale heat treatment industries across the country.

The GL/RL/FL series glass rotor flowmeter produced by Changzhou Liangbang Instruments adopts German production technology. The shell is made of aluminum alloy material, lightweight and convenient, and lined with PTFE plastic for acid and alkali resistance. It is suitable for use in highly corrosive chemical raw materials. Such as sulfuric acid, alkaline solution, sodium hypochlorite, etc. It has excellent characteristics such as strong temperature and pressure resistance, precise measurement, a trumpet shaped scale tube at both ends, a thin tube in the middle, and a scale tube that is not easily broken during use

Our company has the following 5 characteristics to ensure that every flowmeter is of high quality:

1. Our company has professional gas bell covers to ensure that every product is a genuine standard product.

2. Precision parts such as float needle valves are machined by machining centers (CNC)

3. The core components and equipment are all controlled by our company

4. Innovation in welding process industry, single-sided welding and double-sided forming

5. More than 1/4 of the national measurement and testing units use our company's standard flow meters

The upper limit working pressure and upper limit working temperature of FA10 glass rotor flowmeter are higher than those of the original LZB/LZJ series glass rotor flowmeter products with the same diameter; There are two types: ordinary type (measuring generally non corrosive fluids) and corrosion-resistant type (measuring corrosive fluids). The product has a small volume, lightweight structure, beautiful appearance, easy maintenance, safety and reliability, and simple installation. F10、 20. The 30 type flange is rotatable and matches the flange hole of the on-site pipeline.
The GL/RL/FL glass rotor flowmeter can replace the glass rotor instrument on imported complete sets of equipment and is widely used in chemical, light industry, pharmaceutical, food, papermaking, metrology testing, scientific research and other departments to measure the flow rate of single-phase non pulsating fluids (liquids or gases).

When installing a glass rotor flowmeter, the following points should be noted:

1. When receiving the glass rotor flowmeter, first observeGlass rotor flowmeterIs the glass tube inside intact, as glass tubes are prone to damage. Next is to remove the fixed object and gently tilt it to see if the rotor can slide freely up and down. If it cannot slide freely, gently vibrate the support plate so that it can generally slide. If it can no longer slide, professional technicians need to dismantle the machine to solve the problem.

2. When installing on a pipeline, the first thing to consider is whether the downstream pipeline is in a straight line. If it is not on a straight line, it will not only affect the measurement accuracy of the instrument, but also damage the instrument.

3. After ensuring that the first two points are correct, you can start using them. The operator should read the instruction manual carefully before use. When opening the valve, be sure to slowly open it. If it is estimated that the flow can float the rotor but the rotor does not move upward, stop immediately and continue opening the valve. At the same time, gently tap the pipeline to allow the rotor to slowly rise. Many operators opened the valve too forcefully, causing damage to the glass tube inside the glass rotor flowmeter when they installed new equipment. This should be noted by users.

4. The glass rotor flowmeter must be installed vertically on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °. When installed horizontally, the horizontal angle is better than 2 °;

5. For the convenience of maintenance, replacement of flow meters, and cleaning of measuring pipelines, metal tube float flow meters installed on process pipelines should be equipped with bypass pipelines and bypass valves;

6. There should be a straight pipe section of at least 5 times the diameter at the mouth of the glass rotor flowmeter, and a 250mm straight pipe section at the outlet;

7. If the medium contains ferromagnetic substances, a magnetic filter should be installed; If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;

8. When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float;

9. In order to avoid deformation of the flow meter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flow meter. The pipeline support should be used to avoid pipeline vibration and reduce the axial load of the flow meter. The control valve in the measurement system should be installed downstream of the flow meter:

10. When measuring gas, if the gas is directly discharged into the atmosphere at the outlet of the flowmeter, a valve should be installed at the outlet of the instrument, otherwise a pressure drop will occur at the float, causing data distortion.

11. When installing instruments with PTFE lining, do not tighten the flange nuts asymmetrically at will to avoid deformation of the PTEF lining;

12. Instruments with LCD displays should avoid direct sunlight on the display as much as possible to avoid reducing the lifespan of the LCD; Instruments powered by lithium batteries should avoid direct sunlight and high temperature environments (≥ 65 ℃) as much as possible to avoid reducing the capacity and lifespan of the lithium battery.
