MaxiFloTM KM Series Metal Tube Rotameters are rugged, versatile and accurate variable area (VA) flow meter offering 2.0% full scale accuracy. It’s based on simple and easy-to-understand flow measuring principle but is versatile in the types of fluid it can measure and site conditions, under which it can be installed. The meter is manufactured to the user’s application specifications. So, there’s no configuration or calculation required at the time of installation or operation. So, it’s simple to install and operate. The flow rate is indicated on a scale with a needle that is coupled to the rotating float using a magnet. Using potentiometer circuitry, the meter can output 4-20mA signal for flow rate, which can in turn be used to display the instant flow rate and the totalized flow on a digital LCD and output pulse signal for the accumulated flow. It can also output alarm contact signal for low and/or high set points for flow controlling processes. Various materials can be used for wetted parts. So, the meter can handle almost all liquids and gases that are highly corrosive. Also, the meter can be used for hazardous areas using Ex-Proof enclosure option.
