MEASURING PRINCIPLE Having no moving or mechanical parts in the flow profile electromagnetic flow meters cause no pressure drop, are virtually maintenance free and provide highly accurate and stable measurement of liquids with even solid particles inside. Measuring principle is based on Faraday’s law of Induction. Conductive liquid flowing through magnetic field induces voltage proportional to its flow speed. This voltage is picked up by electrodes and measured in converter. Fortunately, most liquids are conductive to some extent but oil products, distilled water, pure alcohol, etc. cannot...

FLOW CONVERTERS M910 comes with six isolated outputs – pulse, frequency, current loop, relay, RS232, RS485 – and one isolated input for exact dose measurement. All fully customizable. 2x16 LCD screen can display min., max. and actual flow rate, directional volumes, auxiliary volume counter, datalogger data and can be used to operate and calibrate the unit by hand. Additional functions include signal filtering (low flow cut-off, moving average), RTC and diagnostics. M910E is economic version of M910 with the same accuracy but limited functionality and user control. Suitable for automated...

Space and cost saving solution with converter mounted directly on top of sensor. – Protection IP67 – PN10 – PN40 – PTFE or hard rubber liner – CrNi steel, hastelloy or tantalum electrodes Separate flow converter can be placed outside installation site for better accesibility. – Sensor and convertor connected by cable – Maximum cable length 60m – Sensor protection IP68 – Convertor protection IP67 – PN10 – PN 40 – Same selection of liners and electrodes Ex certified remote sensor can be installed in workplaces with potentially explosive atmosphere. – Same layout as remote version – Zone II,...

Liner, electrodes and grounding rings come in direct contact with measured liquid so they have to be resistant to its abrasive and corrosive effects. Generally speaking, more expensive materials like PTFE, Hastelloy C276 or tantalum are resistant to more solutions than basic materials but one should always consider compatibility of selected materials with the specific liquid in question. For more details on chemical compatibility see M910’s manual on our website. Diameter selection There are two parameters to consider when choosing diameter of the sensor. First of all, both expected minimum...

Grounding rings Electromagnetic flow meters measure very low voltages so any electromagnetic noise in measured liquid can lead to wrong readouts. Grounding rings can help you avoid this, particularly in systems with plastic or concrete pipes. The rings go between sensor flange and pipe flange like shown. Compact / Remote conversion set Remote set is used for conversion of M9xx flow meters from compact to remote version, compact set does the opposite. Sets contain all parts and description how to convert the flow meter from one type to another. Spare sealing compound Re-enterable insulating...

- Real resistors switched by relays - Custom temperature scales - No residual resistance - 0.01°C accuracy - Six different languages - GPIB, USB, RS-232 and ethernet interface M631 is programmable real-resistance decade with parameters designed specifically for RTD sensor's simulation and testing of RTD evaluation units like temperature regulators, transducers, etc. The core function is still resistance so you can as well calibrate ohmmeters and other resistance based meters easily. With it's 0.01 °C accuracy and 0.001 °C resolution the M631 is rather a laboratory reference but thanks to...
