Description

The delivery set includes: – educational and research stand; – laboratory table with a retractable panel for a laptop; — laptop; – description of laboratory work; – passport combined with the stand operating manual. The stand allows you to measure the pressure and flow characteristics of pumps and a pumping station based on a combination of pumps, set and determine the pressure and fluid flow at various points in the hydraulic system.
Pressure is measured using analog pressure sensors with secondary devices — indicators; the stand uses absolute pressure sensors.
Liquid flow is measured volumetrically, using a water meter, using a diaphragm with a differential pressure sensor with digital display.
