Glass float flowmeter use and maintenance points

1. Anti-corrosion glass float flowmeter is a direct reading instrument, the scale of the conical tube is directly for the flow scale, which can be read directly according to the float height.

Derive the flow rate value.

2. flowmeter into operation, the front and rear gate valve should be opened slowly to prevent the liquid from ramming the float and destroying the instrument. With bypass people should first open the bypass valve, followed by placing the instrument. After the instrument begins to run, slowly turn off the bypass valve.

3. When the density of the medium to be measured, viscosity or temperature, pressure and flowmeter calibration of the substance is different, be sure to calibrate its flow value.

4. flowmeter in normal operation, generally no maintenance adjustment. After long-term operation, instrument maintenance only need to maintain the cone tube and float cleanup, if necessary.

5. Remote metal tube float flowmeter in normal operation, only run to adjust the converter export zero, the other generally do not adjust.

Overall, for Chengfeng instrument, just knocking a few words, but for the majority of users, this is some very practical common sense, perhaps one of them, so that users solve the problems encountered when using. Chengfeng instrument is willing to develop together with friends from all walks of life, and deal with the problems and requirements of each flowmeter customer in a timely manner with heart.

Knowledge expansion.

New electromagnetic flowmeter application after a period of time, must be regularly maintained and maintenance, found unable to receive the signal and signal weakness and other problems, attentively carry out the following process can be handled.

1. First determine whether the pipeline is full of liquid

2. Carefully select the dense part of the pipe, sufficient polishing, wipe with enough coupling agent to install the probe

3. If the pipe is too close to the wall, you can install a probe on the diameter of the pipe at an angle inclined, rather than unnecessary.

When installed on a flat pipe diameter, pick z method to install the probe

4. electromagnetic flowmeter inner wall scaling serious metal pipe can be used to strike off the scaling part.

Gap, but please note that this method will sometimes not assist the transmission of ultrasonic waves because of the gap between the scale and the inner wall

5. Each carefully and slowly move each probe near the installation point to find the large signal point to prevent the installation point of the strong signal due to scaling on the inner wall of the pipe or partial deformation of the pipe and miss the ultrasonic beam reflection prediction area.
