Use a Micronics PF D550 portable Doppler flow meter from HMA Instrumentation 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 flow meter is not required or as a temporary replacement for installed flow transmitters.

The ultrasonic sensor of the Micronics PF D550 portable Doppler flow meter from HMA Instrumentation 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 bubbles or solids. It is ideal for wastewater, slurries, sludge and most chemicals, acids, caustics and lubrication fluids. With its internal battery, the Micronics PF D550 portable Doppler flow meter from HMA Instrumentation can be operated all day and then recharged overnight. For continuous use it can be powered by a supplied 110 V AC to 240 V AC wall plug adapter. A 300 000 point data logger is built-in.
Features include:

• Displays, data logs, transmits and totalises flow in closed pipes
• Fast, easy flow measurement with non-contacting ultrasonic sensor
• Versatile, easy to use
• Ideal for problem liquids
• Three 4-20 mA outputs
• Two control relays
• Measures reverse flow
• Works in irregular channel shapes
• Simple five-key calibration
• 300 000 point data logger
• 4-20 mA output
• Ten-digit totaliser
• AC/DC operation
• Built-in rechargeable battery

Each Micronics PF D550 portable Doppler flow meter from HMA Instrumentation comes complete with rugged watertight strap-on sensor and stainless steel mounting kit. Use the simple five-key menu system to select units of measurement and to calibrate to any pipe diameter 12.5 mm or larger. The recommended pipe diameter is 150 mm.

Sensor mounting and a full calibration can be done in just a few minutes, so it is fast and easy. Put coupling compound gel (included) on the sensor face and mount the sensor on the outside of a pipe with the stainless steel mounting bracket (supplied). Use the five-key calibration system to enter pipe diameter and to select your choice of engineering units (litres, etc.) The Micronics PF D550 portable Doppler flow meter from HMA Instrumentation will begin to display, transmit and totalise immediately.

Sleep mode extends battery life for long-term data logging at locations where AC power input is not available. Between logging intervals, the Micronics PF D550 portable Doppler flow meter from HMA Instrumentation drops into standby mode until a flow reading is requested by the data logger. Flow rates are sampled continuously for ten seconds, whereafter it returns to sleep until the next logger point is required. With five minute sample intervals, it can data log for about 18 days on battery power.
