HT110 Bypass Flowmeter & HXLSensor
|
Designed for ease of use in the critical care setting, the HT110 Bypass Flowmeter and Sterile
Tubing Flowsensor monitor volume flow through medical tubing in intensive care and outside the surgical field in the operating room. Clamp-on
sterile tubing sensors do not compromise tubing sterility or non-thrombogenic surfaces.
By providing reliable, immediate volume flow
measurements, the Bypass Flowmeter system enhances safety for the patient by insuring accurate delivery in procedures using roller pumps, centrifugal pumps and
pressuredriven circuits.

 Transonic XL Sensors
Ultrasonic transit-time sensors, specifically designed for tubing,
measure volume flow with highest accuracy. Most non-aerated liquids can be measured including saline and buffer solutions,
blood, water and even diesel fuel. No physical contact is made with the fluid media.
XL-Series Flowsensors can be calibrated and programmed for up to 4 different fluid
/ temperature / tubing combinations and will work with most flexible tubing types. Sensor size is determined by outside diameter of the tubing.
