2.4.4 CONNECTING THE FLOWMETER – 162FM (OPTIONAL)
The FlowMeter – 162FM is optional for flow measurements in the range of 15 – 4000μl/min. The
FlowMeter is easily combined with any Pressure Myograph System as illustrated in figure below. The
162FM Flowmeter can be obtained as a stand-alone Flowmeter or build into the Pressure Interface.
Use of the FlowMeter permits control of intravascular pressure, pressure gradient and flow conditions
with high accuracy. This enables in vitro studies on vessel segments under conditions very close to those
found in vivo. Adding the FlowMeter to the Pressure Myograph System also enables measurement of
flow rate as a parameter. The FlowMeter data will make it possible to record live traces of the flow
dependent parameters as shear stress and vascular resistance due to changes in vessel structure and
function in various physiological and pharmacological studies.
To add the stand-alone FlowMeter to the Pressure Myograph System the cable from the flow is attached
to the “Flowmeter” port marked on the backside of the Pressure Interface. MyoVIEW will recognize the
FlowMeter as soon as it is connected to the Pressure Interface and will be ready for use immediately.
The External DMT 162FM Flowmeter is connected at the P2 side of the 114P/112PP chamber using the
applied silicone tubing with the internal diameter of 1mm. Connect the P2 outlet from the 114P/112PP
chamber with the DMT 162FM Flowmeter Inlet and then connect the DMT 162FM Flowmeter outlet with
the P2 connection on the Pressure Interface (see in figure below).
