Air flow meters

Caudalímetros de molinete.

Based on rotation of a rotor with blades against the action of the air flow, los caudalimetros de molinete are are highly reliable in occasional fixed flow measurement in duct air circulation.
Easy installation and low sensitivity to variation of working conditions, we can find two types; large blades or installation in the exit of the canal or the micro-winch for insertion into the duct.
Amongst the whole range, we would like to highlight low cost standard versions and the more robust models prepared for work in high temperature, harsh environments or ATEX areas.

Thermal flow meters

Based on the principle of thermal dispersion or hot wire, they enable the measurement of the speed of the air in ventilation ducts, HVAC systems or other indoor measurements.
We can measure small speeds with high accuracy.
They have an amplified analogic output of 4/20 mAdc, 0/10 Vdc, 0/5 Vdc, etc.
We have diverse versions from the low-cost made of plastic for undemanding applications to high resistant models.
