Correct Use Is The Foundation Of The Use Value Of Glass Rotameter

The reading of the glass rotor flowmeter is clear, direct, reliable, simple in structure, easy to maintain, and durable. This is a commonly used measuring instrument in industry, has been widely used, and can provide more help for the development of many industries. When operating the instrument, the user should master the correct method of use. The structure of the instrument is simple and the operation is convenient, but the correct use is the foundation of the instrument's use value.

1. During transportation, transportation and installation, the glass rotor flowmeter must not be hit or knocked to prevent the glass tube and glass plate from breaking.

2. After installation, when the medium temperature is high, do not open the valve immediately, preheat for 20-30 minutes, and then slowly open the valve after the glass tube reaches a certain temperature. Valve opening steps: first slowly open the upper valve, and then slowly open the lower valve, so that the measured medium slowly enters the glass tube.

3. When using a glass rotor flowmeter, the dirt on the inner and outer walls of the glass tube should be cleaned regularly to keep the liquid level indicator clear. Cleaning procedure: first close the upper and lower valves connected to the container, open the drain valve to drain the residual liquid in the glass tube, and then use a suitable cleaning agent or a long rod brush to clean the dirt on the inner wall of the tube.

4. If the quartz tube is broken or severely scaled and needs to be replaced, the specific steps are as follows: remove the main body of the workbench, loosen the nuts at both ends, knock one end of the quartz glass tube to the other end, take out the graphite ring with a wooden stick, and install a new one. Put the graphite ring on the quartz tube, insert the graphite ring into the meter body at equal intervals, tighten the nut and the nut, and then confirm that there is no leakage before putting it into use.
