Dual & Single Channel Flowmeters

Ultrasonic Transit Time Research Flowmeters for Quantitive Fluid Flow Measurements

Transonic Systems Inc. is the manufacturer of ultrasonic transit time research flowmeters used for quantitative fluid flow measurements. Their flow meters utilise an advance transit time technology to measure volume flow in vessels. This technique is different to conventional doppler ultrasound. Transonic flowmeters measure volume flow directly with perivascular flowprobes for acute and chronic measurements; and extracorporeally in tubing with in-line and sterile tubing (clamp on) flowsensors. Single and dual channel flowmeters are equipped with analog and digital displays to monitor volume flow and ultrasonic signal coupling. Pulsatile and average flow signals are simultaneously accessible via analog outputs.

T106/T206 Animal Research Flowmeters

This series of flowmeters is optimised to provide high resolution volume flow measurements in any species where the capability to monitor flow vessels under 1.0mm in dia-meter is desired. Miniature 1mm R-series flowprobes enable direct monitoring of peripheral vessels in the rodent model. Expanded capabilities for these flowmeters permit monitoring of vessels up to 20mm in diameter. Streamlined connectors are available for minimal trauma in chronic implant. In-line (N-series) flowprobes compatible with the T106X/T206X for Langendorff preparations, isolated perfused organ studies and extracorporeal circuits include the 1mm N-series flowprobe with .05ml/min resolution. Sterile tubing (C-series) flowsensors are compatible for flexible laboratory tubing from 1/8" up to 3/4" diameter.

HT107 Single Channel & HT207 Dual Channel Flowmeters

These flowmeters operate perivascular flowprobes for vessels 2mm to 48mm diameter. Advanced acoustic monitoring adjusts the sampling rate of flowprobes for local acoustic conditions, eliminating potential error from received echoes, minimising zero offset for large probe sizes and maximising frequency response. In-line (N-series) flowprobes are available for laboratory tubing up to 1 1/4" in diameter: Sterile tubing (C-series) flowsensors for extracorporeal circuits may be manufactured for tubing up to 1" I.D.

Note: A newly released single or dual channel clinical flowmeter with FDA approval allows measurement of coronary, carotid, hepatic (arterial and venous) and general vascular flow.
