Oval Wheel Flow Meter OVM - 1

Benefits • accuracy 1 % of measured value • Volume measurement 2-60 l / min • independent of density / temperature / viscosity • compact design, no inlet and outlet sections are required • dosing function through the use of a PLC connection Intended Use • for accurate measurement of flow rates • for dispensing liquids (electronic control unit or PLC required) Application • chemical and industrial plants Function • Oval Wheel Flow Meter belong to the group of direct volumetric meters for liquids with movable partition walls (displacement flow meters). • The Oval Wheel Meter consists of a measurement chamber housing with two pivoted oval wheels which are toothed and roll off each other in counter-rotations. • Each revolution the oval wheels displaces a discrete volume of liquid (defined by the space between the oval wheel and measurement chamber) through the chamber. • For measurement purposes, the rotation of the oval wheels is transmitted to a mechanical counter and/or a pulse pick-up via a magnet coupling and gear device. Application Media • Neutral and aggressive fluids free of solid particles, provided that the valve components coming into contact with the fluids are resistant at the operating temperature in accordance with the ASV resistance guide. Viscosity • max. 40 mPa s Nominal Pressure (H2O, 20°C) • PN 6 Fluid Temperature • see pressure-/temperature diagram Operating Pressure • see pressure-/temperature diagram Size • DN 25 Case • PP-n (natural polypropylene) Sealing • EPDM Oval Wheels • PEEK Axis • Al2O3 (99,7%) Measuring Value • flow rate Measuring Range • 2-60 l/min Revolutions Per Liter • 20 n/l Pulses Per Revolution • 2 Imp/n K-Factor • 40 Imp/l Repeatability • < 0,5 % Tolerated Deviation • 1 % of measured value Influence Of Ambient Temperature • included in the measuring deviation Pick-Up Sensor • Reed-contact (e.g. for connection to evaluation electronics or a PLC of the user) • max. switching capacity 1 W • max. switching current 0.1 A • max. switching voltage 30V AC/ 30V DC Type Of Protection • IP 65 Mounting Position • The housing cover of the Oval Wheel Meter is to be placed vertically so that the axes of the Oval Wheel are in a horizontal position independent of the position of the pipe. Process Connection • threaded socket Rp 1" > data sheet no.: 330661 - 2013/01/24 ASVStubbe GmbH & Co.

Oval Wheel Flow Meter OVM - 2

Level measurement, Oval Wheel Flow Meter OVM Pressure/temperature diagram Electrical connection Pin assignment Reedsensor R1 P = operating pressure T = temperature The pressure/temperature limits are applicable for the stated nominal pressures and a computed operating life factor of 25 years. These are standard values for harmless media (DIN 2403), to which the valve material is resistant. For other media please refer to the ASV resistance guide. The durability of wear parts depends on the operating conditions of the application. For temperatures below 0°C (PP < +10°C) please specify the...
