Pressure-sensing digital flowmeters provide a way for plant personnel to monitor pressure throughout a compressed-air system along with flow. A pressure sensor is mounted between the two flow-sensing probes, and the display can be configured to show air pressure or airflow. A transistor output can also be configured to provide a low-pressure alarm to protect your processes and/or equipment. Measuring compressed air is the first step toward identifying high compressed-air-use areas, compressed-air leaks and optimizing air use. Each flowmeter ships with the necessary hardware and tools for installation, including drill bit, drill guide and hex wrenches. Airflow values are expressed in standard cubic feet per minute or cubic meters per hour.
