Flapper Nozzle System

The product enables study of working principles of Flapper-Nozzle system.

Features:

• Simple and compact setup
• Micron dial gauge for flapper movement

Range of Experiments:

• Study of Flapper-Nozzle system
• Gain calculation of Flapper-Nozzle system

Descriptions:

The set up helps in understanding conversion of mechanical motion to pressure signal. It consists of flapper-nozzle mechanism, Dial gauge indicator, pressure gauges and air filter regulator. A regulated supply of pressure, usually over 20 psig, provides a source of air through the restriction. The nozzle is open at the end where the gap exists between the nozzle and flapper, and air escapes in this region. As the flapper moves down and reduces the nozzle gap the signal pressure increases. The graph of signal pressure verses nozzle gap can be plotted and system gain can be calculated. Setup is compact and table top mountable provided with soft copy instruction manual, software program for plotting test results and sample calculations.
