Turbine flow sensors for liquids, series Turbotron

DN 25 ... compact and reliable!

Turbotron VT 25 with pulse output

The turbine flow sensors of the product line Turbotronare sensors for flow rate measurement or dosing applica-tions for liquids. Through its especially compact type, itsvery wide measuring range and its convincing precisionof measurement, it has an almost unlimited application.Especially suitable and proven in numerous serial appli-cations through

Convincing advantages

?

fixed pulse rate, thus practically no serial deviation

?

wide measurement range 1:45, universally usable

?

high-quality sapphire/PA bearing, low abrasion andextremely long running period

?

any position, can be versatile installed

?

available materials: plastic, brass and stainless steel,thus suitable for numerous applications

?

plug adapter or fixed connecting cable.The liquid which flows through the flow sensor, makesthe turbine wheel rotate. The high-quality saphire-bea-rings and the low rotation rate provide the turbine withan exceptional life time. The rotation of the rotor is now converted into an electri-cal pulsed signal (frequency):

Design and function

?

VTH and VTM have rotors which are equipped withmagnets. A Hall-sensor recognizes the rotation of therotor.

?

The rotor of VTI is equipped with stainless steel pins.An inductive proximity switch detects the rotation ofthe rotor.In both cases, a flow-proportional frequency signal(square wave signal) is available. Schematic representation-8-
