Description
Overview
GAOTek digital air flowmeter adopts piezoelectric crystal as testing components. It is a new kind of stress detecting air flowmeter. It has the advantages of wide speed, wide range rate, high accuracy, low pressure loss, good medium generality, pulse signal output proportional to flow, convenient to connect with computer etc.
Features
- It is easy to carry with one hand
- Different types of application
- It has a resistant material: stainless steel
