Overview
Benefits
* Bi-directional flow measurement of liquids and gases
* Cost effective: No pipe work, no process shut-down, maintenance-free
* Zero-point stable and drift free - Carefully matched and temperature compensated transducers (fully ANSI / ASME compliant)
* Retrofittable - No pipe modification required, no process shut-downs
* Maintenance Free - Free of wear & tear and abrasion, not prone to clogging or corrosion, no fugitive emissions
* High tolerance to entrained solids and gas wetness
* Independent of pipe size, material, operating pressure, and gas composition
* Flexible configurable outputs
* Advanced Meter Verification
