The metal tube flowmeter is used in daily industrial production is widely used instruments, because it is all-metal structure, low pressure drop design department for gas and liquid measurement walks of life, for harsh environments and severe corrosion medium, good heat resistance and pressure resistance. However, the structural characteristics rotameter itself against impurities contaminated in some media, rotameter is not applicable, if such impurities into the measuring tube, it needs to be cleaned.
Since the float inside the bag has a permanent magnet, the iron impurities within the pipe easily adsorbed on the surface, not so easy to make the float jammed fluctuate. When the float stuck avoid banging measuring tube surface and the transducer portion, particularly the small-diameter, thin tube measuring meter. Measuring tube may cause irreparable damage or limit change concentricity ring and beat guide in the process, causing the float stuck. Float in the cleaning process as an important cleaning objects
Gently remove the collar, with the needle nose pliers to remove the stopper ring, hand to block the exit of the measuring tube, slowly measuring tube upside down, felt float slide, it will remove it. Use of water, gas or dry cloth to clean the surface impurities, and the measuring tube and stopper ring with cleaning. After completion of the float when you press the open order light load measuring tube. DN15 float vertical guide rods are cylindrical, can be measured after gently shaking the float into the tube, it falls within the guide, but we must distinguish between the upper and lower float can not hold against; DN25 and above the guide rod diameter under milling flat at an identification of direction should be aligned at milling flat guide groove to be loaded, and then align the stopper ring on the float guide rod is loaded, the card ring snaps into the groove, If the collar is too loose, you can hand to gently stretch out the collar, but not excessive force. After all assembled, push the float view pointer rotation flexibility.
Cleaning Note
Remove and clean the float process, the attention can not float drop, knock, smashing, etc., throughout the cleaning process should be gently lightly armed, to prevent causing misalignment and down and scrapped. The float will not be close to a strong magnetic field, so as not to change the polarity of the float is determined collar fall collar slot to prevent the meter when measured by the impact of the media, the float, stopper ring and collar off when mounted in the collar inside into the pipe, causing damage to the rear end of valves, pumps, etc., lead to unnecessary losses. Converter section indicating no moving parts, do not open when cleaning.
