Vortex Flow Meter Principle

Vortex Flow meter Animation

A vortex flow meter comprises a flow sensor to sense pressure variations due to vortex-shedding of a fluid in a passage and measure flow rate.

4-20mA Current Loop

Basics of 4-20mA Current Loop

The 4-20 mA current loop is a very robust sensor signaling standard.  Current loops are ideal for data transmission because
