Ultrasonic Flow Meter: Doppler Ultrasonic Flow Meters Directory
|
The Ultrasonic Flow Meter: Doppler Ultrasonic Flow Meters Directory section from Process Controls and Instrumentation Buyers Guide is a comprehensive directory resource. An ultrasonic flowmeter (non-intrusive Doppler flow meters) is a volumetric flow meter which requires particulates or bubbles in the flow. Ultrasonic flowmeters are ideal for wastewater applications or any dirty liquid which is conductive or water based. Ultrasonics flowmeters will generally not work with distilled water or drinking water. Aerations would be required in the clean liquid applications. Ultrasonic flowmeters are also ideal for applications where low pressure drop, chemical compatibility, and low maintenance are required. The Ultrasonic Flow Meter: Doppler Ultrasonic Flow Meters Directory offers a comprehensive range of ultrasonic flow meters from industry leading manufacturers. |

Measure flow from outside a pipe. The Greyline DFM 5.0 is designed for "difficult liquids" that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The non-intrusive, clamp-on ultrasonic sensor fits any pipe 1/2" (12.5 mm) Inside Diameter or larger. The electronics/display enclosure can be mounted nearby. |
 |
PDFM 5.0 Portable Doppler Flow Meter It's ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. The new PDFM 5.0 is fast and easy to operate – you can mount the sensor on the outside of a pipe in less than a minute. Use the built-in keypad and calibration menu to set up the flowmeter for your application. |
 |
Control Flow from outside a pipe. Recommended for "difficult liquids" including wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. The Greyline DFS-II is ideal for pump protection or to activate flow/no-flow alarms. |
 |
PT400 Portable Ultrasonic Flow Meter Recommended for clean fluids like water, glycol, oil and most chemicals. Sensors can be mounted without shutting down flow and there is no obstruction or pressure drop. The ultrasonic signal travels through all common metal and plastic pipe materials. Flow rate and totalizer are displayed continuously along with battery status, signal strength. |
 |
The PTFM 1.0 ultrasonic transducers strap-on the outside of pipes from ½" to 48" (12 to 1200 mm) diameter. The ultrasonic signal works through common pipe materials including carbon steel, stainless steel, ductile iron, cast iron, PVC, PVDF, fiberglass, copper, brass, aluminum and pipes with bonded liners including epoxy, rubber and Teflon. Transducers can be mounted without shutting down flow and there is no obstruction or pressure drop. |
 |
TTFM 1.0 Transit Time Flowmeter Accurately measure the flow rate of clean, non-aerated liquids like water, chemicals, and oils in full pipes. Ultrasonic transducers mount on the outside of a pipe without shutting down flow. Flow rate is displayed on the large, backlit display along with totalizer and signal strength. Use the built-in control relays for flow alarms or flow proportionate pulse. Connect the isolated 4-20mA output to PLC's or controllers. |
 |
Ultrasonic Flow Meter Sonic-Pro The Sonic-Pro series Hybrid Ultrasonic Flow Meters can measure fluid flow in virtually any fluid in which sound waves can travel. The Sonic-Pro meters are considered “hybrid” because they can measure fluid flow using either the Doppler or Transit Time methods. The Sonic-Pro ultrasonic sound transducers are clamped to the outside of the pipe wall and include no moving parts. This method of flow measurement is safe, non-intrusive and very easy to service. |
