Frequently Asked Questions
Dwyer provides a wide range of industrial measurement and control instruments, including pressure gauges, mechanical switches, manometers, flow switches, and flow meters.
No. The breathable material naturally prevents moisture condensation, eliminating the need for extra insulation in standard operating conditions.
Introduced in 1953, the Magnehelic® gage revolutionized low-pressure measurement by utilizing a diaphragm-based mechanism. This design provides high accuracy and versatility while serving as a reliable, maintenance-free alternative to traditional liquid-filled manometers.
Dwyer flow switches are designed to monitor set flow rates and trigger electrical contacts or alarms when flow stops or exceeds a threshold. Flow meters and sensors provide real-time, continuous measurement and tracking of fluid or air flow rates.
