Flow meters

F-2500 Series Vortex Mass Flow Meters provide accurate, direct mass-flow measurement of steam, compressed air, and gases without the need for an external flow computer. Continuous real-time density calculations are performed internally using integral flow, temperature, and pressure-sensor data. A two-stage bluff body/sensor design enhances signal sensitivity and extends meter operating range.

Variable-speed drives

Altivar 12 variable-speed alternating-current drives deliver flexibility, performance, and energy efficiency in a compact design. The drives feature starting and stopping motor performance that eliminates the need to oversize a drive or add dynamic braking in most HVAC applications. The drives also can rapidly detect motor-current peaks.

Solar control circulator

For the clean-energy solar-thermal market, the Variable Speed Solar Control Circulator continuously optimizes water flow through a solar collector to achieve maximum energy gain. The circulator maximizes energy gain by maintaining the proper delta-T through a solar collector over an extended period of time. The circulator continuously adjusts its speed, maximizing the output of a collector while increasing usable higher-temperature water throughout the day, eliminating short cycling and increasing performance by 20 percent.
