The Atrato inline low flow flowmeter is utilizing patented technology that enables it to operate with excellent accuracy over very wide flow ranges, across the whole span. It is a genuine breakthrough in flowmeter technology. Its rugged, clean bore construction makes the Atrato ideal for a whole range of low flow applications and its USB port allows software connectivity at literally the touch of a button. The Atrato is a low flow flowmeter and can handle low flows from laminar to turbulent and is largely immune from viscosity. It has excellent turndown, repeatability and linearity. Accuracy is better than ±1.0% of reading. The USB connection permits the user to directly monitor the rate and total on their laptop as well as altering some of the operating parameters, such as the pulse resolution and units. Read more
