Dwyer Instruments
Dwyer Instruments covers the practical middle of process and building instrumentation: flowmeters, analog pressure gauges, dial thermometers, pressure and flow switches, controllers, air flow measurement and differential pressure devices.
Dwyer is the line most often specified for HVAC balancing, filter monitoring, duct pressure and general plant indication, where robustness and a sensible price matter more than laboratory accuracy. Selection usually comes down to three things: the range, chosen so normal operation sits mid-scale, the wetted materials against your medium, and whether you need local indication only or a transmitted signal. Tell us the medium, the line size and the output your control system expects.
