ALTAIR V4

Product catalog summary

Application
ALTAIR V4 is a new generation volumetric meter designed under the MID (Measuring Instruments Directive) to meet field requirements. It is compact, suitable for restrictive environments like water boxes, and robust enough to handle various water qualities. The meter is modular, allowing integration with IZAR RADIO, IZAR DOSING, or IZAR PULSE systems.
