Installation Method for Liquid Tanks

This measurement approach is compatiblewith ‌most liquid tanks‌. The sensor can be ‌directly threaded into the 

mounting port (standard thread: ‌M18×1.5‌ per ‌ISO 1179-1‌)for secure fixation. Key requirements:

1、‌Vertical Installation Orientation‌ (tolerance: ±2° deviation)

2、‌Sealing‌: PTFE tape (EN 751-2 compliant)

or O-ring (NBR/FKM material optional)

3、‌Torque‌: 25–30 N·m (using DIN 3129 standard wrench)
