Introduction MIE magnetic-inductive flowmeters (compact version: MIE-C, separated version: MIE-S) are precise measuring devices intended for the measurement of liquid flow of electrically conductive media. The meters may be used for measurements, registration, dosing, mixing, etc. Applications Water management, drinking and waste water measurement ...
Technical conditions Measurement conditions Measurement is independent up on: Liquid temperature and pressure Liquid density and viscosity Solids contents Usual level of magnetic field interference For maintaining the MQI accuracy and reliability, it is necessary to meet the following conditions: ...
Main unit option Control and evaluation electronics is assembled into robust aluminium housing with IP67 protection, or in case of remote version, protection of sensor is IP68. Additional option (customer request): Multi-point calibration of the measuring range. The flowmeters are usually calibrated in 3 points. On the customer‘s request, the number of calibration points can be increased.
Tolerance of built-in lengths: DN 10 ÷ DN 150 → A ± 5 mm, DN 200 ÷ DN 1000 → A ± 10 mm Signal cable (connection between sensor and converter of the MIE-S): Signals which are transmitted from a sensor electrode circuit to the converter will be in a range of millivolts.
It is recommended that the flow direction should follow the arrow on the sensor cover; the converter is also preset for this direction. On the operating meter, it is possible to adjust the reverse flow direction by changing the MIE converter parameter. ...
Recommendations for installation To avoid any measurement errors which are caused by air bubbles or failures on the lining, pay attention to the following recommendations: During assembling correctly seat the sensor, tighten screws uniformly and move on a diagonal one after another.
Tightening all cable connection clamps and plug in all connectors. For MIE-S verify the completeness of the shipped set according to the serial numbers of sensor and converter. Verify proper supply voltage; see the label on the converter.
The delivery can be carried out by a public carrier, the transport of the customer or the import by the production organization. The costs are paid by the customer.

8 data bits, even parity, one stop bit. Each MIE register takes two MODBUS registers, i.e. each MIE register is 32 bits long. These 32 bits are interpreted as an integer with or without a sign or as a floating point number with single precision. Double precision floating point numbers are stored in eight bytes, so they are transmitted in four MODBUS registers.
Modbus registers All registers are read only. For security reasons writing to registers is a bit more complex than reading, so the manufacturer provides configuration software which is free to charge. Address Type Name Unit Description [dec] [hex] 0064 unsigned int Slave address Slave device address in range from 1 to 247.
