1.3. Safety Instructions Please read this manual carefully before using the product. Keep this manual for future reference. Arkon Flow Systems, s.r.o. will not be liable for any damage caused by improper use of the product or its accessories. If the device is used any different way than is specified, the electric protection may be disrupted. -
Page 5: Installation
All MAGS1 sensors are supplied with 2 built in earthing electrodes that are sufficient for all applications with metal pipes and tanks. However on applications where all pipes and tanks are manufactured from plastic, it is recommended that earthing rings are also installed to ensure the maximum resistance of the sensor to earth is <1 ohm. -

OK (min) - the minutes count the device measured correctly. Diameter – nominal sensor diameter that is currently configured for the given flowmeter. Firmware No. – firmware version of the meter. Flow Qn – expected nominal flow. MAGS1 User Guide V1.5 22-1-2016... -
Page 18: User Settings
Samples per Avg. – the number of samples that the flowmeter will use for calculation of its displayed average flow value. Low Flow Cutoff –the minimum flow the flowmeter will react on. Setting is done in percentage of Qn. Invert Flow – possibility to change direction of the flow displayed. MAGS1 User Guide V1.5 22-1-2016... -

Page 22: Self-Cleaning Electrodes
6. Self–cleaning electrodes If mechanical cleaning is not possible, MAGS1 has an electrolytic method to clean electrodes. An electrolytic method is advantageous for its simplicity; however it can only be applied for the contamination that can be removed by electrolysis. (Low contamination and deposit) 24VAC voltage is applied directly to sensor electrodes to clean them. -
