Below are general answers on typical components of a manometer from the list of GAO Tek’s manometers. To facilitate our customers to select our products, we have further classified our manometers by their features: data logging, error indicator, handheld, high accuracy, USB connectivity, and wireless.

We have products in stock and can ship overnight to most places in the U.S. and Canada.

Fluid Column: The fluid column is the primary medium through which pressure is measured using a GAO Tek manometer. Common fluids used in our manometers include mercury, water, and oil. The choice of fluid depends on the pressure range being measured and the compatibility with the substances being measured.

Manometer Tube: This is the tube in which the fluid column is located in our manometer. The design and shape of the tube depend on the type of the manometer. For example, a U-tube GAO Tek manometer has a U-shaped tube.

Scale: The scale is a calibrated marking on the manometer tube that allows for the measurement of the height of the fluid column. It is typically graduated in units of pressure (e.g., inches of mercury, millimeters of water).

Reservoir: Mechanical Component: In some of our manometers, especially those designed for high-pressure measurements, a reservoir may be present to provide additional fluid to the system and maintain a stable reference level.

Pressure Inlet/Outlet Ports: These are the points where the pressure to be measured is introduced into the manometer. The design and number of ports depend on the specific type and application of the manometer.

Pressure Measurement Device: In modern GAO’s manometers, we used electronic pressure sensors or transducers to convert the mechanical pressure into an electrical signal. This signal can then be processed by us and displayed digitally.

Data Display: Digital GAO Tek’s manometers may have an electronic display to provide a numerical readout of the pressure. Analog manometers may have a gauge or pointer on a scale.

Microcontroller or Processor: In our digital manometers, a microcontroller or processor is used to handle the electronic signals from the pressure sensor, perform any necessary calculations, and control the display.

Power Supply: Digital GAO’s manometers require a power source to operate. This can be a battery or an external power supply, depending on the design and application.

Software: Some of our advanced manometers includes software for calibration, data logging, or communication with other devices or systems.
