![]() ![]() As standard, the current flow rate and the flow velocity are displayed in one metric unit. It is also possible to adjust the individual display settings. After the supply voltage is switched on, the Gemü 3030 mFlow is at the working level, where the most important system parameters are displayed. Two levels are available for operating the device using the front keyboard. All that is needed is a standard browser and a current operating system. No special software is required for browser operation, as this is already integrated in the meter. In addition to the uncomplicated and fast installation of the Gemü 3030 mFlow, commissioning is simple, with versatile operating facilities, for example using the fascia buttons with illuminated display, PC connection with Internet browser and fieldbus interfaces. However, if required in order to adapt to plant-specific conditions, the magnetically inductive flowmeter can be recalibrated on site, which improves its accuracy at the same time. The assembly fittings are suitable for all standard process connections and can be combined with one and the same measurement device.Ĭalibration at the factory ensures the flowmeter is immediately ready for operation once the operating voltage has been connected. These requirements are particularly important in the pharmaceutical and foodstuff industry, but also in the mining industry where pipes without constrictions are advantageous because of abrasion and deposits. In-line housings by Neumo and Tuchenhagen are suitable for this purpose. ![]() If required, a deadleg-free measurement or a measurement with full flow bore can be achieved. A bolt hole is simply drilled into the piping so that the weld-in sleeve, the adaptation device for the unit can then be welded in place.Īpart from the weld-in sleeve, in-line housings and wafer-type flanges can be used as fittings. Nominal sizes from DN 25-300 can be covered with this one device. The accompanying weld-in sleeve enables the meter to be installed in a variety of piping. This makes it possible to detect any connection problems in the fieldbus system or faulty data transmission of a device quickly and easily. The two visual indicators, integrated in the housing, indicate the status of the Profibus connection. ![]() Status information, error messages and the operating range can be displayed and operated simply and easily thanks to these interfaces. The Gemü 3030 mFlow can be optimally integrated in fully automatic plant control systems using standard signals (analog output 4-20 mA and pulse output 24 VDC) to transmit the flow rate to higher-level plant systems and interfaces such as the RS-232 and Profibus DP. The system is connected electrically using standard connectors which are fitted to the back of the flowmeter as 5-pin M12 connectors, making it easy to connect without needing to open the housing. Simple connection to the plant control system ![]() Thanks to the low installation depth of the sensor, there is only a negligible loss in pressure. The magnetically inductive flowmeter can be used up to a maximum operating pressure of 10 bar and the ambient temperature should not exceed the range 0 to 60☌. The flowmeter operates reliably with conducting media in the temperature range of 0 to 135☌ with a supply voltage of 24 VDC and an automatic adaptation of the measuring range (0–4 m/s or 0–10 m/s). Furthermore, the measurement result is largely independent of process pressure, temperature and viscosity. Flow velocities of 0,1–10 m/s are measured. The flow rate is then calculated using the pipe cross section previously entered by the user. This makes it possible to measure the flow velocity of liquids precisely. The flowing medium, which must be electrically conductive, (20 μS/cm) is the moving conductor. With this measurement principle, a moving conductor induces a voltage in a magnetic field which is proportional to the speed of the medium. Magnetic induction as a measurement principle Thanks to its varied applications, the Gemü 3030 mFlow is a more cost-effective option than some conventional flowmeters. Compact and flexible components, available at low cost, are in high demand in the plant engineering sector. ![]()
