Ultra-low flow measurement
Measure liquid flow from 15 to 4,000 µL/min in arteries, veins, small ducts and other tubular preparations.
Pressure Myograph Accessory
Ultra-low flow measurement for pressurized vessel studies
The DMT FlowMeter – 162FM enables fast, calibrated measurement of ultra-low liquid flow through intact tubular preparations such as arteries, veins and small ducts under dual pressure control. When combined with a compatible DMT pressure myograph and MyoVIEW, it connects vessel-diameter changes with real-time flow, shear stress and vascular resistance.

Flow measurement add-on
Why choose 162FM
Add calibrated flow data to pressure-myograph experiments
Vessel diameter alone does not always describe the complete functional response. The 162FM adds a direct flow measurement that can be interpreted together with pressure, vessel dimensions and experimental interventions.
Stable volume-based technology
CMOS-based volume measurement supports stable and accurate readings in vascular research workflows.
Temperature compensated
Flow data are calibrated and temperature-compensated by the internal microcontroller.
Pressure-myograph integration
Add flow to compatible DMT pressure-myograph workflows without changing the underlying cannulated-vessel approach.
Why flow matters
Interpret vessel diameter together with functional flow
During a pressure-myograph experiment, the vessel may constrict or dilate in response to pressure, luminal flow or a pharmacological intervention. Adding direct flow measurement helps establish how those diameter changes affect fluid movement through the vessel.
MyoVIEW can combine diameter, pressure and flow measurements to support real-time calculation of vascular resistance and shear stress.
Flow rate
Measure liquid movement through the mounted tubular preparation
in real time.
Diameter response
Relate changes in vessel lumen and external diameter to the
measured flow response.
Shear stress
Use MyoVIEW to calculate shear-related values from flow and
vessel-dimension data.
Vascular resistance
Evaluate how pressure, vessel diameter and flow combine to
determine functional resistance.
Dual pressure control
Measure flow through tubular tissues while controlling pressure
on both sides of the preparation.
