4.3 Installation
The flowmeter can be installed on horizontal, vertical or inclined pipes, and at any angle in the circumferential direction
of pipes, but it's necessary to consider the convenience of operation and maintenance.
For dirty or humid gases, it's recommended to install the flow meter horizontally (up) to reduce the possibility of
contamination of the sensor. The installation position of the sensor should avoid the lowest part of the pipeline to prevent
the water from accumulating in the pipeline and make the flowmeter unable to work properly.
Installation Position
●Upstream distance should be 10D while downstream 5D. If there is a gas rectifier on pipeline or the gas flow rate is
less than 30 m/s, upstream distance can be 5D and downstream can be 3D.
●Explosion-proof areas are prohibited from fire. If the pipes are not weldable, special clamps can be used to fix the
sensor on the pipe. Manual drilling tool is used in the explosion-proof area and electric drilling tool is used in the safe
area.
●The arrow direction "→" on the sensor housing should be consistent with the flow direction of gas. The insertion
direction of the sensor should be perpendicular to the flow direction of gas.
●Do not install the flowmeter in places with strong vibration.
●Do not share power with equipment that contaminates the power supply such as inverters, welders. If necessary,
install a power conditioner for the transmitter.

Mounting Extension Tube
The connection of extension tube can be divided into welding type and clamp type according to different pipe materials
(weldable and non-weldable). If the pipe material is cast iron or non-metallic, the extension tube can not be mounted by
welding. In this case, the special fixture provided by the manufacturer (the extension tube is welded to the fixture) should
be used. The size of the fixture depends on the outer diameter of the pipe.
●Welding type
1. Locate the apex of the pipe and adjust the threaded extension tube (G1-1/2" threaded extension tube or M33 * 2
threaded extension tube) to the apex to make the axis of the threaded hole passes through the apex and is
perpendicular to the axis of the pipe.
2. Weld the threaded extension tube to the pipe by welding machine. It must be welded firmly, and no welding defects
such as slag inclusions and air holes are allowed.
Note: If air cutting is used, the base should be welded after tapping.
●Strap-on type (Saddle fitting (carbon steel))
1. Place the fixture on the pipe and locate the apex of the pipe and adjust the threaded base to the apex to make the
axis of the threaded hole passes through the apex and is perpendicular to the axis of the pipe.
2. Tighten the two nuts on the clamp to ensure that they will not loosen after locking.

4.3.2 Drilling Hole
Check the installation environment carefully before drilling hole to ensure safe operation. After the hole is drilled, close
the valve in time to avoid air leakage.
●Stop production
When the production is stopped, there are many ways to drill holes. The diameter of the hole should not be less than 22
mm, and the axis of the hole should be concentric with the axis of the hole of the extension tube. After drilling the hole,
tighten the stainless steel valve to the extension tube. (G1-1/2" / M33 * 2 threaded extension tube is sealed with gasket)
●None-stop production
If on-line drilling is needed, the special drill tool of our company can be used to achieve on-line installation. The special
drill tools include manual drill tool and electric drill tool. Manual drill tool are required for use in an explosion-proof
environment.
The following is a brief description of how to use the electric drill tool.
1. Tighten the stainless steel valve ①to the extension tube and open it.
2. Hold the cavity nut ③and move the rod body ②upward so that the drill bit ④can return to the cavity nut ③.
3. Connect cavity nut ③with stainless steel valve ①and pay attention to tightening and sealing the thread.
4. Push the rod body ②down to the pipe wall and connect the electric drill ⑤to the top of the rod to start drilling.
5. After drilling, remove the electric drill ⑤and then adjust the rod upward until the rod remote from the stainless steel
valve ①. Close the stainless steel valve ①and turn the cavity nut to remote it from the valve. The drilling is completed.

4.3.3 The Installation of Plug-in Flowmeter (Hot Tap Tape)
1. Loosen the lock nut ④on the sensor rod to enable the
cavity nut to slide along the sensor rod ③to the sensor
sheath ⑨so that the sensor sheath ⑨can fully retract
into the cavity nut ⑥.
2. Fasten the cavity nut ⑥to the ball valve. (The G1-1/2"
threaded base is sealed with a gasket)
3. Open the stainless steel ball valve and insert the sensor
rod into the pipe.
4. Insert the sensor rod into the pipe until it reaches the limit
boss. Turn the sensor rod to make the direction of the arrow on
the flowmeter is consistent with the flow of the medium, and then
lock the lock nut ④.
Note: Please insert the sensor sheath ⑨into the center of the
pipe during use.
To ensure that the sensor sheath ⑨is inserted into the center
of the pipe, please measure the total length L of the sensor rod.
After insertion, the length of the rod outside the pipe should be
I = L-1 / 2DN - wall thickness.
So it's required to design the length of the extension tube
before the installation.

4.3.5 The Installation of Pipe Type Flowmeter
The production should be stopped during installation and the connection of the pipeline (flange or threaded) should be
confirmed.
The sensor has been assembled on the special pipe before leaving factory. Users only need to assemble the pipe to the
site, which is simpler than the installation of the plug-in flowmeter. During installation, please cut the pipe and install the
mating flange according to the length of the sensor. Lock the flange hole by bolts and install the pipe type flowmeter on
the pipe. Please note that the flow of the medium should be consistent with the direction of the arrow on the flowmeter.

If there are relatively more pulses need to be output, and the pulse output circuit cannot output in
time, the pulses that are not output in time will be kept in the pulse counting buffer. The buffer size
is adjustable from 0 to 59999. When the numbers in the buffer exceeds the set value, the PB0 error
(Pulse Buffer Error) will be triggered. Users can associate this error by setting the Alarm mode or
Alarm mode sub-menu in the Alarm Parameter to achieve linkage alarm after error.
