– Flow output signal
–External voltage control of flow rates

Specifications
Volume flow range8 µl/min–2400 µl/min Power DC supply or battery (9 V), depending on tube set used.

FI-1_FlowIndicator_web_010v1.jpg

Flow Indicator

The FI-1 provides a digital readout of the flow rate delivered by the FC flow control pump or the PS-200 pressure servo control pump. Flow rate can be monitored directly on the front-panel meter in µl/min, or using the analog voltage output signal, which is compatible with most data acquisition systems. The FI-1 also has a connector that enables remote control of flow rate using a D/A output or other analog voltage source.

Specifications
Flow rate0–25 through 0–500 µl/min ranges
Standard ranges25, 50, 100, 200, 500 µl/min
Accuracy±3% ±1 µl/min (over 5% to 100% of range maximum)
Precision±1% or 0.1 µl/min
Panel meter resolution±0.1 µl/min
Output signal10 mV/µl/min
Response time< 1 s
Power117 V/60 Hz or 230 V/50 Hz

WINDKESSEL_in-lineLuerReservoir_web_3437v1.jpgWindkessel Reservoir, In-Line Luer , pair

A windkessel is a plumbing component that serves to dampen pressure/flow pulsations. Pulsation dampening is accomplished by introducing a compressible air reservoir into a physiological solution flow circuit. Our windkessels are constructed using a Luer tee fitting that can be connected in-line with your vessel perfusion circuit. The top arm of the Luer tee has the air-filled reservoir that serves to dampen flow/pressure pulsations of the fluid going through the main line of the tee. Windkessels can be introduced on the downstream side of a FC Flow Control Pump, as well as on the upstream side of a PS-200 Pressure Servo Pump in constant pressure/constant flow systems.  Includes two windkessels.
