Flow indicators, also known as sight glasses, are used for visual and quantitative flow indication of liquids and gases. The flowing medium can be observed through a sight glass. For particularly clear liquids or gases, the flow indicators/sight glasses are equipped with rotors, flaps or balls to make the flow visible.
Variable Area Flow meters work on the principle of a float and cone, whereby as the float moves within the cone, the area increases with the flowrate and are used for flow measurement, display and monitoring of a wide variety of liquids and gases. The flow rate can be read through built-in sight glasses with scales. Attached contacts switch reliably at the set switching points. All-metal devices, optionally with pointer display, are available for use at high pressures.
Paddle Flap Flowmeters monitors flows using either an impact disk, paddle or flap to measure the flow of liquids and gases. The deflection of the paddle is proportional to the flow. Built-in contacts, microswitches and measuring sensors are available for further processing of the output signal. The variety of designs, materials and measuring ranges offer a wide range of applications.
Paddle/Oval Wheel, Nutating Disc, Turbine, and Gear Wheel Flowmeters are mechanical devices that use different methods to measure flows. In the case of impeller and turbine flow meters, a moving wheel is driven by the flowing medium (low-viscosity liquids), thus generating a pulse/frequency output according to the flow. Downstream electronics can further process this signal into analog signals and/or switching points. Commonly used for irrigation and cost-effective dosing applications.
Electronic flow meters include magnetic inductive, ultrasonic and calorimetric flow meters/thermal mass flow meters. In addition to the various analog outputs, frequency and pulse outputs and switching points are also available. The flow of liquids and gases is reliably measured with this group of devices.
