MEDAP LS FLOW

Click-stop
flowmeters for
any application

The MEDAP LS FLOW flowmeters have an integrated pressure regulator which reduces pressures between 3 and 5.5 bar to a constant supply pressure. This complex technology results in a significantly higher accuracy of the MEDAP LS FLOW flowmeters than required by the standard.

Setting a tube flowmeter is very time-consuming. It begins with the question as to which point on the ball (top, middle, bottom) is decisive for setting the flow rate, and continues on to setting the control valve millimetre by millimetre. It is almost impossible to make a setting in the decimal range, especially at low flow rates. With a click-stop flowmeter, the desired flow rate can be set quickly and precisely by simply turning the handwheel.

The second advantage is its position-independent function capability. While the flowmeter ball in a tube flowmeter indicates the flow rate accurately only in an absolutely vertical position, a click-stop flowmeter functions regardless of its position. This feature is important, for example, in the case of media bridges in the operating room or for in-hospital transport. Finally, tube flowmeters have a significantly higher risk of breakage. If they fall on the floor, the flowmeter tube usually breaks. Click-stop flowmeters usually survive a fall undamaged and are therefore more robust.

With 13 setting levels, the MEDAP LS FLOW flowmeters have an extremely large number of settings. Comparable products on the market sometimes have only 8 or 9 setting levels. The high number of setting levels allows for the greatest possible individuality. The MEDAP LS FLOW flowmeter version with 0–15 l/min, for example, has three settings below 1 l/min. This feature makes this particular flowmeter ideal for the treatment of children.

With some products on the market, a short burst of oxygen occurs when switching from one flow rate to another; that is, a large amount of oxygen flows to the patient for a very brief moment. Some manufacturers therefore recommend setting the click-stop flowmeter first and only then making the connection to the patient. When switching between two flow rates with the MEDAP LS FLOW flowmeters, a small amount of oxygen flows to the patient (always less than the lower flow rate). This prevents short bursts of oxygen.
