Vertical InstallationHorizontal Installation
(1) Insert two stud bolts in the bolt holes
on the flowmeter shoulder to align
the instrument body with the inner
diameter of the adjacent piping.
(2) Tighten all bolts uniformly and check
that there is no leakage between the
instrument and the flanges.

Vertical Installation
When Installation Collar are required, the
installation vortex flowmeters applied to the
following line sizes and flange ratings.
The inside diameter of the gasket must
be larger than the pipe inner diameter
so that it will not disturb the flow in the
pipeline.
Horizontal Installation
When installing the Flowmeter vertically in the
open air, change the electrical connection port
direction to the ground. If the electrical
connection port is installed upwards, rain
water might leak in.
WARNING
In case of vertical installation, two collars in
the upper part might move after the
installation. But it doesn't influence the
performance, please use the flowmeter under
such condition.
WARNING
WARNING
(1) Insert two collars on each two bolts of bottom side of the flowmeter.
(2) Fit the flowmeter body to the collars. And tighten the four bolts and nuts
uniformly.
(3) Check for leakage from the flange connections.
