Applications

The Digital differential pressure manometer can measure differential pressure/positive pressure/negative pressure and is equipped with a simple hose connection device, suitable for measurement and on-site verification in ventilation and air conditioning systems, as well as troubleshooting in clean rooms or any gas pressure systems. The clear reading of the Digital manometer makes it a valuable tool forHVAC technicians, operational maintenance engineers, and scientific researchers.

Tips: What are the different types of differential pressure manometers available?

• U-Tube Manometer: A U-tube manometer consists of a U-shaped glass or transparent tube partially filled with a liquid, such as mercury or water. The height difference between the two liquid columns in the U-tube is directly proportional to the differential pressure being measured.
• Inclined Manometer: In an inclined manometer, the U-tube is bent at an angle to make it more compact and easier to read. This design is often used when space is limited.
• Well-Type Manometer: A well-type manometer involves a U-tube that is connected to a well or reservoir. The fluid level in the well responds to changes in pressure, allowing for precise measurements.
• Bourdon Tube Manometer: Bourdon tube manometers use a curved tube made of metal that straightens as the pressure difference increases. The deflection of the Bourdon tube is proportional to the pressure difference.
• Bellows Manometer: Bellows manometers use flexible, sealed metal bellows that expand or contract with changes in pressure difference. The motion of the bellows is measured to determine the pressure variation.
• Piston Manometer: A piston manometer employs a moveable piston within a cylindrical chamber. The piston's displacement due to pressure difference is used to determine the differential pressure.
• Diaphragm Manometer: Diaphragm manometers use a flexible diaphragm that deflects in response to pressure differences. The displacement of the diaphragm is converted into a pressure reading.
• Electronic Differential Pressure Manometer: Electronic manometers use pressure transducers and sensors to measure differential pressure. They provide digital readouts and may offer additional features, such as data logging and remote monitoring.
