The smart and lightweight vortex meter
for monitoring low viscosity, water-like liquids
> Introduction
Mass Flow ONLINE B.V. sells flow measuring and controlling products
through the internet. From the website www.massflow-online.com flow
meters or controllers can be ordered 24 hours a day 7 days a week.
Most products are in stock and will be shipped world-wide within
two working days.
> Description
The new LIQUI-VIEW Base series offer a compact, light weight and
cost-effective solution for monitoring the flow or consumption of
cleansing, cooling or spa water. The unique sensor body and
transmitter design makes LIQUI-VIEW Base one of the most
compact, lightweight vortex meters in the industry.
> LIQUI-VIEW Base series
The LIQUI-VIEW Base series operate on the vortex principle. The
obstruction (bluff body) placed in the flow of the liquid sheds
vortices downstream at a frequency proportional to the velocity of
the liquid. This pattern of vortices is named the Von Kármán vortex
street. A piezo-electric sensor detects the vortices and creates
electrical pulses which are proportional to the liquid flow rate.
The instruments may be mounted in any position.
LIQUI-VIEW Base flow meters can be supplied in ranges from
0,5 l/min up to 150 l/min at max. 12 bar pressure rating.
Furthermore the instruments can be supplied with an
analog output or a pulse output.
