500mbar plus two times the fluid vapour pressure. N = Nitrile • If there is any chance of air passing through the system mount the Atrato in a vertical E = EPDM pipe with the flow in an upward direction otherwise air can remain trapped in the meter S = Silicon and affect it’s performance.
Electrical Setup The Atrato can be used entirely from a computer using the USB connection but this Before use, download and install Atrato software from memory stick or website. may not be acceptable in many situations where remote operation or further functions The Atrato low-flow ultrasonic flowmeter should be setup using the USB interface and a are required.

Because of the potential for conflict should the PNP OutPut is selected the check box options are:- output be activated accidentally, Titan Enterprises Ltd recommend a resistor so that the Pulse Flow switch Reverse flow sink current cannot exceed 5mA.
