This manual introduces VERBAR's differential‑pressure flow meters, describing how the probe creates a high‑pressure zone at the stagnation point and a low‑pressure zone downstream, allowing flow rate to be derived from the pressure difference. It also details the bullet‑shaped probe design, integrated one‑piece construction, and the placement of low‑pressure ports to prevent blockage and ensure stable signals.
The document provides performance data (accuracy, pressure and temperature ranges), compares VERBAR probes with traditional orifice plates, and lists various product families (commercial, industrial, high‑temperature/high‑pressure, online) with their connection options, pipe‑size limits and installation instructions. This manual is written in Chinese.
