Comparative Analysis and Selection Guide for Bar-Type Differential Pressure Flow Meters

Pressure Transmitter /

1. Overview Bar-type flow meters, also known as insertion differential pressure flow meters, operate based on Bernoulli’s principle. By measuring the differential pressure generated across the sensor (total pressure minus static pressure), they calculate flow velocity and volume. Their simple structure, low pressure loss, and ease of installation make them ideal for large-diameter pipelines (typically
