Transonic 400-Series
Multi-Channel Research Flowmeters

Applying our core ultrasonic transit-time technology, the PXL Clamp-on Tubing Flowsensors revolutionized blood flow monitoring in medical devices by providing reliable non-invasive volume flow measurements in flexible tubing from 1/8” OD to 1 ¼” OD. No contact is made with the fluid media and their clip-on operation makes it easy to maintain a sterile circuit. Their X- transducer design ensures accurate measurement of pulsatile flow as well as steady state conditions. Transonic PXL Flowsensors guarantee years of productive use and uncompromising quality of measurement. PXL sensors are custom calibrated for up to 4 selectable combinations of user parameters (tubing type, fluid, temperature & target flow range). Calibration Certificates are supplied with every sensor.

• PXL Clamp-on Flow Sensors operate on TS410 Tubing Flow Modules
• 1/8” OD to 1 ¼” OD in 1/16” increments to fit OD of flexible tubing
• Accuracy +/- 10% of flow reading; flow resolution scaled to sensor size
• Custom Calibrated for user needs

For highest accuracy and circuit design flexibility, Transonic PXN Inline Flowsensors splice into tubing lines and measure the flow within. PXN Inline Flowsensors utilize a scheme of ultrasonic illumination that makes it possible to manufacture a flow-through sensor with a smooth cylindrical interior without compromising measurement accuracy.  Sensors are available in sizes from 1 mm ID to 25 mm OD to complement most laboratory requirements. Small 1, 2, 3 mm sizes have flexible tubing ends to couple with laboratory canulae in isolated organ applications; large sizes have rigid barbed ends to fit standard flexible laboratory tubing. PXN sensors are custom calibrated for up to 4 selectable combinations of user parameters (fluid, temperature & target flow range). Calibration Certificates are supplied with every sensor.

Product Details:

• PXN Inline Flow Sensors operate on TS410 Tubing Flow Modules
• 1 mm ID to 25 mm ID splice into laboratory tubing
• Accuracy +/- 4% of flow reading; flow resolution scaled to sensor size
• Custom Calibrated for user needs

Transonic’s COnfidence Flowprobes for large animal studies have been the “go-to” instrumentation to measure in vivo cardiac output for over a decade and have surpassed all previous flow probe designs for the ascending aorta and pulmonary artery. Gold standard ultrasonic transit-time technology with validated X-pattern full flow illumination is enhanced by a flexible probe liner to cushion the vessel, permitting sustained ultrasound transmission in acute experiments and long term implantability in chronic studies. COnfidence Flowprobes offer unsurpassed beat-to-beat measurement accuracy on vessels with highly dynamic and irregular flow profiles such as the great arteries.

Product Details:

• Sizes 8, 10, 12, 14, 16, 20*, 24*, 28*, 32*, and 36* mm specifically sized for large vessels.
• Reusable transducer shell with easy-to-use, single-use Ultrafit Liners
• Custom calibration available for synthetic grafts and implanted VADs 

*These Flowprobes come with two Ultrafit Liner sizes for improved fit. Additional Ultrafit Liner sizes are 18, 22, 26, 30, and 34 mm respectively.

COnfidence Flowprobe Specifications

Transonic’s PS-Series Flowprobes are the robust, tried-and-true ultrasonic transit-time flowprobes that researchers have relied upon for their cardiovascular studies for decades. Accurate, high resolution blood flow measurements are largely independent of vessel diameter or vessel/probe alignment. With the flowprobe’s unique non-constrictive fit and multiple configuration options, there’s a probe for every artery, vein or vessel duct that you wish to explore. These probes can measure blood, lymph, urine, and other physiological fluids with remarkable stability and accuracy, even at significantly low flow rates. PS-Series Flowprobes are also suitable for long term implantation.

• Sizes 0.5*, 0.7*, 1.5*, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16 and 20mm
• Both acute use and custom configured for chronic implant
• Unparalleled accuracy & signature high resolution flow waveforms
• Gold standard transit-time ultrasound volume flow technology
• Not for use in humans.

*0.5, 0.7 and 1.5 mm PS-Series Flowprobes are considered Nanoprobes and are subject to limitations due to their delicate nature, see PS-Series Nanoprobes for more details.

Flowprobe Specifications

Nanoprobes are special miniaturized PS-Series Flowprobes designed to fit mouse anatomy. These Flowprobes are able to measure volume flows < 1 mL/min with Transonic’s signature high resolution quality in vessels as small as 0.3 mm in diameter.

Product Details:

• Sizes: 0.5 mm, 0.7 mm & 1.5 mm
• Both acute use and custom configured for chronic implant
• Tiny Probe heads to better fit in limited surgical space
• Reflectors are delicate and must be handled with care
• High resolution at low flows
• Not for use in humans.

PR-Series Flowprobes are based on the original ultrasonic transit-time Flowprobe innovation that allowed accurate blood flow measurements independent of vessel or Probe alignment with a non-constrictive fit. 

Product Details:

• Sizes 1 mm & 1.5 mm
• Both acute use and custom configured for chronic implant
• Custom calibration available
• Unparalleled accuracy & signature high resolution flow waveforms
• Not for use in humans

Flowprobe Specifications

Transonic’s V-series Flowprobes are designed for acute microcirculation studies where small second & third order vessels 0.5 to 0.7 mm diameter can be isolated and studied under strict stable conditions. These flowprobes use a unique mirror ultrasonic path to amplify flows in small vessels. Note: vessels must fit completely in the V-groove of the flowprobe reflector for accurate measurement. The airspace between the vessel and probe transducers must be filled with gel. Provided with a stainless steel handle to be stabilized in a micromanipulator.

Product Details:

• Sizes: 0.5 mm, 0.7 mm
• Acute use only
• Robust design
• Larger Probe head than PS-Series Nanoprobes requires more acoustic couplant
• High resolution at low flows
• Not for use in Humans

Flowprobe Specifications

PMP-Series Handle Flowprobes match the Flowprobe style used in clinical vascular surgeries to get the same fit, form and feel as in the clinical OR. PMP-Series Flowprobes are ideal for testing medical protocols or devices in the preclinical setting. The handle has a flexible neck so the Probe head may be positioned as required. The open J-reflector encircles the vessel for momentary flow readings.

Product Details:

• Sizes 2, 3, 4, 6, 8, 10, 12 and 14mm
• Acute use only
• Requires acoustic coupling gel to fill the air space between the probe and vessel
