Summary
The invention discloses a manufacturing method of an electroplated diamond grinding wheel, which is composed of a steel base body and an electroplated grinding layer. The invention has the advantages that: the diamond powder of various crystal forms which are roughened is used as an abrasive to improve the fixing force of the coating alloy on the abrasive grains; in addition, a solid lubricant is added to the grinding coating layer, which effectively reduces the The heat generated by friction between the grinding wheel and the optical component during use avoids the hidden danger of burnt scrap of the precision optical component due to high heat.

Site Selection for Mass Flow Meter Installation
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
