Thanks to its special design and the epicycloid wheels, the EPI flowmeter is highly precise and allows extremely accurate flow measurement with minimal pressure loss.Included in the delivery:3-pin solenoid socketItem number: 941-0002/3Specific applications: Highly viscous media, high temperatures, high flow rates with low pres-sure loss and good chemical resistance.Material:Housing: PEEK 150 GL 30 naturBearing pin: Inox 1.4435 Aluminium oxide on requestO-ring: FPM (Viton) EPDM on requestTurbine: PEEKMagnets: NdFeB (Neodym) (not in contact with the medium)Technical data:Flow rate: 0.06 - 16.0 l/min depending on viscosityMeasuring accuracy: +/- 1.0% depending on viscosityRepetition: <+/- 0.25%Temperature range: -10°C to +65°C 14°F to 149°FPressure range: 10 bar at 20°C 145 psi /68°FMounting position: Horizontal recommendedNozzle size: Ø 7.0 mmViscosity range: approx. 5 - 8000 centistokesDimensions in mm:Electrical connection ratings:Power supply: 4.5–24 V DCConsumption: 5 mA to max. 13 mASignal connection: Open collector NPNSignal voltage: 0 V GNDSignal load: max. 20 mALeakage current: max. 10 µAConnections: 3-pin AMP 2.8 x 0.8 mmSignal: Square-wave outputDuty Cycle: 50% / ±3% Special regulations which must be complied with by the flowmeter manufacturer apply to each coun-try, e.g. CE, NSF, FDA and SK. The various media flowing through the flowmeter differ from applica-tion to application. You are advised to enquire with the medium manufacturer as to whether the entire installation and the flowmeter are resistant to the medium itself (see Material)RESISTANCEDIGMESA electronic circuitry is always designed for operation with DIGMESA flowmeters. Please note the following if connecting to other elec-tronic circuitry:•The flowmeter does not supply an output voltage but switches the signal terminal to 0 V ground (actuated) or leaves it open (non-actuated)•There must be a pull-up resistor between power supply + and signal depending on electronic circuitryELECTRONICApprovals / StandardsEN55014-1:00+A1:01+A2:02, EN61000-6-3:01+A11:04 , IEC61000-6-3:06(ed.2.0), EN61000-3-2:06, IEC61000-3-2:05(ed.3.0), EN61000-3-3:95+A1:01+A2:05, IEC61000-3-3:94+A1:01+A2:05(Cons.ed 1.2), EN55014-2:97+A1:01, EN61000-6-1:01, IEC61000-6-1:05(ed.2)Digmesa AG, Keltenstrasse 31, CH–2563 Ipsach / Switzerland, Phone +41 (32) 332 77 77, Fax +41 (32) 332 77 88, www.digmesa.comWe reserve the right to make modifications in the interests of technical progress .
