Non-intrusive flow meters

By transit time

The nonintrusive transit time flow meters allow us to measure the flow in pipes through which flows a clean or homogeneous fluid. The measurement of the fluid velocity is made from the alteration of sound transmission in a flow.
The limitation of the measurement is established in non-homogeneous liquids or with a high concentration of particles or ducts constructed in non-homogeneous materials which do not allow proper transmission of sound.

Doppler

The non-intrusive flow meters by Doppler system, measure the flow in full pipes where circulates a fluid with minimum particles or bubbles.
The speed of the flow is determined by the measurement of the forward speed of particles.
La limitación de la medida se establece en límpios with absence of bubbles or suspension particles or ducts constructed in non-homogeneous materials which do not allow proper transmission of sound
