DWYER INSTRUMENTS Manometers

Dwyer Instruments U-tube manometers are used for measuring the flow rate of air in a pipe. These manometers combine the inherent accuracy of a U-Tube with the durability of tough, long-lasting plastic construction. They are designed to measure positive, negative and differential pressure values and are easily accessible for cleaning services. These units are backed by a white scale channel to provide maximum color contrast. Choose from a wide range of these U-tube manometers available in pressure ratings up to 100 psi, on Raptor Supplies, an authorised Dwyer Instruments distributor.

Frequently Asked Questions

How do I maintain these manometers?

  • Regularly calibrate the manometer to ensure accurate measurements.
  • Clean the manometer's housing and display using a soft cloth and non-abrasive cleaning solution.
  • Protect the manometer from extreme temperatures, humidity and excessive vibration.
  • Store the manometer in a clean, dry place when not in use.

Are there digital versions of Dwyer Instruments manometers available on Raptor Supplies?

Yes, Dwyer Instruments offers digital manometers alongside traditional analogue models. Digital manometers provide the advantage of easy-to-read digital displays, enhanced accuracy and additional features, such as data logging, pressure unit conversions and selectable engineering units.

How do Dwyer Instruments manometers work?

Dwyer Instruments manometers work based on the principle of fluid displacement. These devices typically consist of a U-shaped tube filled with a liquid, such as mercury or a coloured fluid. When pressure is applied to one side of the tube, the liquid moves and creates a measurable height difference between the two arms of the U-tube. The height difference corresponds to the pressure being measured.
