3 VARIABLE AREA FLOW METERS These flowmeters operate according to the variable area principle, where a float is suspended in upward flowing media in a tapered plastic tube. The vertical position of the float within the metering tube depends on the flowrate of the media. The measuring range is usually 1:10 where the scale is uniformly graded on the measuring tube. The measured value is determined by the upper edge of the float and can be easily read on the scale. The rotameter is suitable for liquids and gases and it provides a cost effective solution for flow measurement in l/h, Nm³/h, %, or other units. On request double scales are also available, such as l/h and %. SED offers attractive components for contactless monitoring and automatic detection such as the Reed Contact Switch and especially, the measuring sensor for continuous data acquisition, programmable via touch panel. MAIN FEATURES Wide choice of measuring scales Wide choice of end connections Eight different diameters Five different tube lengths Three different plastic tube materials SS and PP float materials Special and double scales available Good level of accuracy with simple operation Easy to maintain Accessories Transmitter for the continuous contactless measurement acquisition Reed switch for contactless monitoring of measured values CLASSIFICATION liquid gas long short PVC PA PSU INSTALLATION DETAILS When the flowmeter is used in a system provided with control valves, the following criteria must be observed: With liquid media, isolating or control valves may be mounted both upstream or downstream the flowmeter With gaseous media, control valves are recommended to be mounted downstream the flowmeter All control valves must be open slowly and gradually due to the high sensitivity fo the float to flow variations. Flowmeter must be mounted vertical VERSATILITY Metering tubes are available in Trogamid (PA), suitable for inert media, PVC and Polysulfone (PSU) suitable for many corrosive media. Male threads moulded onto the end of the metering tube are used for easy mounting of unions. Standard unions are in PVCU but others are available according to the different working conditions. The floats are available in Stainless Steel (AISI 316 Ti) and PP depending on flow medium and measuring range. All the flowmeters are equipped with minmax visual flow indicators fully adjustable. In addition, the flowmeters can be fitted with minmax flow switches or measuring sensor. When fitting the electrical accessories, a float with magnet must be installed in the flowmeter. 0

11 ACCESSORIES MEASURING SENSOR Measuring sensor for all types of variable area flowmeters suitable to be applied to liquids and gases. The measuring sensor provides a continuous signal of the flow throughout the complete measuring range. The sensor detects the floater position even with nontransparent or turbid media in the flowmeter EasyFlow. The continuous position detection is carried out with several magnetic field sensors over a length of up to 00mm. The measuring sensor is installed via a modular mounting clip concept on all Easyflow standard types. Due to the product design, the scale still remains visible. The parameterization of the sensor is possible by pushing capacitive buttons. Further possible settings include the activation of MIN/MAX indicator bar, the individual adjustment of the analog process signal (010V or 0/40mA) or the brightness of the LED bar display. With a 5pin M1 connector as an electrical interface, a supply voltage of 4V DC and the device protection class IP67, the measuring sensor can be used in many areas of plant automation.

12 ACCESSORIES Variable area flow meter (as option) Measuring sensor

13 ACCESSORIES MICRO SWITCHES The micro switches are clamped on the guide of the flowmeter. A bistable reed contact is built into the switches and it is activated by the magnet incorporated into the float. The bistable magnetic micro switch is used as a position indicator for floats in SED flowmeters. Measurements can be expressed contactfree and nonreactive. The micro switches, with IP65 protection class, are available for MIN or MAX flow rate indication with a different design according to flowmeter sizes. MAX control switch /.055 It closes when the MAX threshold is overshot upward. 1 MIN control switch /.065 It closes when the MIN threshold is overshot downward. 1 CLASSIFICATION Type flowmeter ArticleCode 700/ /751 DN /751 DN Reduced height on request Reduced height on request
