Flowmeters

An extensive range of flowmeters is available to measure volume flow through arteries, veins and ducts of different species and of diameter 0.25 mm and upwards.

Tubing and perfusion applications are also possible.

All models provide calibrated analog signals (in flow units) that can be directly connected to any type of data acquisition systems, such as iox2 software..

Description

Perivascular tubing flows – The T400 Serie

Standard features of all 400 series flowmeter modules:

  • “Average volume flow” display
  • “Received signal strength” bars
  • One-push button for easy zero adjustment
  • Low-flow button to increase sensitivity 4 times
  • 0.1, 10, 40, 160 Hz filter settings
  • Front-panel BNC analog flow output
  • 8 analog output signals on back panel terminal block including: pulsatile flow, mean flow, received signal quality, phase & synchronization
  • External synchronization
  • Voltage range: ± 5 volts
  • Ultrasonic frequency range: 600KHz to 14.4 Mhz

TS420 Flow Modules offer an unmatched range of precision flow probes for vessels 0.25 mm and larger. It measure absolute blood flow in arteries, veins & ducts for acute & chronic cardiovascular research applications:

  • Cardiac output and cardiovascular dynamics
  • Renal hypertension
  • Carotid thrombosis
  • Stroke models
  • Hemorrhagic shock
  • Ischemia/reperfusion
  • Portal hypertension etc.

Transonic Systems’ TS410 Flowmeter Module with PXL-Series sterile tubing flow sensors provide unparalleled volume flow measurements in tubing applications including:

  • Extracoporeal shunts and cannulas
  • Fluid phantoms and mock circulatory models
  • Artificial heart and VAD performance
  • Pulse duplication/heart valve studies
  • Isolated perfused organ studies

Different type of probes are available:

  • 0.5 to 0.7 mm perivascular nanoprobes for mice
  • Precision probes for any vessel
  • V-Series probes for microvessels – acute studies
  • Flowprobes for Cardiac Output
  • Handle probes

Perfusion flows – The BLF Series Laser Doppler flowmeters

Transonic Systems’ BLF-Series perform continuous microvascular perfusion measurements in 1 mm3 of tissue for real-time assessment of perfusion.

Flowmeters monitor the effects of exercise, drug treatments, environmental or physical manipulations on target microvascular beds…

Dual channel units can monitor an experimental tissue along with a control or a second area of affected tissue.

There are two basic types of Laser Doppler probes: For acute use and for chronic application.

Continuous measurements can be taken in skin with surface probes; intra-operatively in organs with surface, straight or needle probes; and internally with endoscopic probes. The monofiber probe can be used to measure perfusion with fibers implanted in tissues of laboratory animals.

A variety of probes are available. Type DI, I, M, R, S probes are nonmagnetic. Type N can be made of brass with a diameter of 1 mm. All can have cables as long as needed to isolate instrument from the magnet.
