The Digital Flowmeter has an LED display that directly indicates the SCFM of airflow through that pipe (other flow meters require the reading to be multiplied by a specific conversion factor to be accurate). Two models are available for use on Schedule 40 iron pipe – one designed for 1″ Schedule 40 iron pipe and the other for 2″. Each Digital Flowmeter is calibrated for the specific pipe size it is mounted to.
The Digital Flowmeter is designed for permanent mounting to the pipe. It requires the user to drill two 3/16″ diameter holes through the pipe using the included drill bit and locating fixture. The two flow sensing probes of the flowmeter are inserted in these holes. The unit seals to the pipe once the two clamps are tightened. No cutting, welding, adjustments or calibration are ever required.
