Use a PF D550 Portable Doppler Flow Meter to monitor and balance flow, or to troubleshoot flow problems in full pipes. It is ideal to evaluate performance of in-line flow meters and can be installed, calibrated and started-up in minutes. Use it for projects where a permanent flowmeter is not required or to temporarily replace installed flow transmitters.

The PF D550 ultrasonic sensor is clamped on the outside of a pipe. An acoustic pulse is reflected back to the sensor from particles or gases in the flowing liquid. The flow rate of any fluid can be measured as long as it contains air bubblers or solids. It is ideal for wastewater, slurries, sludge and most chemicals, acids, caustics and lubrication fluids. With its internal battery the PF D550 can be operated all day and then recharged overnight. For continuous use it can be powered by a supplied 110-240VAC wall plug adapter. A 300,000 point data logger is built-in.
