Can the LGF-PA66 Be Installed on Vertical Pipes?

Yes. The LGF-PA66 supports horizontal, vertical and inclined mounting, but three rules must hold:

• Flooded first: the measuring tube must always run full. On vertical runs the flow should go bottom-to-top, so the pipe stays flooded at low flow or when a pump reverses; top-to-bottom vertical mounting is not recommended - the tube may not stay full and accuracy suffers.
• Keep the electrode axis horizontal: on horizontal pipes, orient the two measuring electrodes on the horizontal centerline (never straight up/down), so gas bubbles cannot collect on the upper electrode and sediment cannot blanket the lower one.
• Meet straight-run requirements: >= 5D upstream and >= 3D downstream (D = pipe diameter); add more upstream length or a flow conditioner when elbows, valves or pumps sit close by.

High points in a pipeline trap air - do not install the LGF-PA66 at the system's highest point; if unavoidable, fit an automatic air vent there. Low-lying valve pits are fine: the LGF-PA66 rating is IP68, supporting long-term immersed conditions.

The transmitter head rotates to multiple angles for easy reading on site; a split-type setup can move the transmitter outside the pit for convenient maintenance, linked to the sensor by dedicated shielded cable.
