Revolution among Bopp & Reuther oval wheel meters Oval wheel meter Series Miniflow: Technical perfection for a very convincing price conceived for process applications: • direct measurement of the volume or of the flow rate • very rugged design • high flexibility and adaptability • high accuracy and high resolution • modular design • low installation costs Measuring principle Series Miniflow devices are positive displacement meters from type oval wheel meter and have been designed for the measurement of extremely small volumes resp. volumetric flow rates. These devices are offering a high flexibility in the field, due to their modular design. Series Miniflow oval wheel meters have an exceptionally rugged design and are characterised by their simplicity and userfriendlyness. Their innovative construction is the conjunction between decades of know-how together with most recent technologies. A Series Miniflow oval wheel meter consists of the following main components: - stable housing with axis and oval wheels - cover (a transparent version allows to see the rotation of the two oval wheels, thus allowing to use the Miniflow as a flow indicator) - modular sensor system (different pulse pick-ups, Universal Smart Transmitter, local indicator MFE) Technical data Accuracy (Viskosität >1mPas) Repeatibility Operating temperature Ambient temperature Process connection Electrical connection Output Display Materials Protection type EX-Protection EG-certification, standards, approvals <± 1% o. r. without calibration <± 0,5% o. r. with calibration 0,1% of reading -10°C to +70 °C -10 °C to +60°C (blind version) 0 °C to +50°C (local indicator version) Female thread G1/8“ or G1/4“, PN10 or PN40 Other type on request NAMUR pulse pick-up: 8,2 VDC Magnetic field sensor: 10-30 VDC Universal Smart Transmitter: 14-30 VDC Pulses (Open Collector or NAMUR), Reed contact or 4-20mA/HART and pulses (NAMUR) Universal Smart Transmitter UST with HART-commun., Digital local indicator MFE Wetted parts: stainless steel, Aluminium, PPS, Makrolon (transparent cover), ceramic (axes), other on request IP 67 (blind version) IP65 (local indicator version) Pulse pick-up II 2G EEx ib II C T6 acc.NAMUR: Universal Smart II 2G EEx ia IIC T6 Transmitter UST: II 2G EEx d [ia] IIC/IIB T6 II 2G EEx de [ia] IIC/IIB T6 acc. EMV-Richtlinie 89/336/EWG, 92/3/EWG, 93/68 EWG, EN 50081-1, EN 50082-2 and NAMUR NE 21 Miniflow with magnetic field sensor Measuring range Measuring range 0,1 to 1 l/min Applications The oval wheel meter type Miniflow is usable for simple, reliable and economical measurement of very small liquid volumes or flow rates in all kind of branches of the industry. Thanks to the available material combination, series Miniflow also allow to deal with agressive and corrosive liquids like acids in the process industry. In addition these meters show a very high resolution in the range of about 3100 pulses/liter. Branches: mechanical constructions, engineering, food industry, semiconductor industry, environment, automobile, laboratory, test plants Media: oils, greases, colors, detergents, gasoline, diesel etc...
