136 ROF

SBEM’s Ultrasonic Rate of Flow Open Channel 136 ROF is an advanced non-contact flow measurement device designed for high-precision monitoring of water flow in Parshall flumes, Rectangular weirs, and Triangular weirs. Utilizing ultrasonic technology, this system calculates flow rates based on liquid level using structured algorithms, eliminating the need for conventional stage-discharge or strap tables. This ensures high reliability, minimal maintenance, and durability in harsh environments. Ideal for applications in irrigation systems, water treatment plants, environmental monitoring, and stormwater management, the 136 ROF offers real-time data, remote communication, and compatibility with ISO-standard installations. Available in split-type mounting, it supports measuring ranges of 2m or 5m with ±0.5% level accuracy and ±5% flow accuracy. With output options like 4–20 mA and RS485, and robust IP68 sensor protection, this product is well-suited for global industries seeking efficient, contactless flow measurement solutions.
