Flowmeter Uses Unique Target System

KOBOLD’s DPT series flowmeter uses a unique, patented target system to measure water flow. Its design uses a single leaf-spring to both suspend the target and to provide the target resetting force. It is described as a simple, reliable design with virtually no wear.


The mechanism consists of a target plate and lever arm. Fluid flow causes the target plate and lever arm to deflect against the leaf-spring. A permanent magnet attached to the lever arm and Hall effect sensor mounted inside the display unit translate angular motion of the target to an electrical signal. Signal from the Hall effect sensor Is then employed by the electronic indicators to provide a flowrate display, adjustable setpoint switches, or an analog flow signal. The target plate measuring system offers a very low head loss. For more details, peruse the DPT series datasheet and user manual.
