2) To install the flowmeters, drill a hole of 35mm diameter into the pipe

having more than or equal to 40mm diameter. Use the three-way socket

for the pipe having 20 to 32 mm diameter. Select and drill the hole at

right place so that the final fixed posture of tapered tube should be

vertical.

3) Weld the socket to the drilled hole. The centerline of the socket must be

perpendicular to the one of the pipe.

4) Screw the CFNW fixing nozzle into the welded socket to complete the

installation.
