New State-of-the-art Flow Transmitter

The MR Flow Transmitter from Hedland (USA) combines stateof-the-art digital signal processing technology with the rugged proven technology of a piston-type variable area flow meter. The solid state design electronically senses movement of the magnetic piston assembly and provides accurate, repeatable flow measurement. The device has no mechanical linkages, which results in longer operating life.

All MR Flow Transmitters come pre-calibrated from the factory. However, the unit may also be configured by the User to meet specific application requirements. Calibration inputs are available for: specific gravity for all fluids; viscosity for petroleum-based fluids; as well as specific gravity, pressure and temperature for pneumatic systems. Combined with User-selectable units of measure, these configuration

functions allow for precise measurement on unique applications.

Additional benefits and features include the transmitter’s non-contact sensor electronics, digital flow rate and total flow indication, proportional analogue output and its low power design, which allows for 2-wire loop powered operation. The MR Flow transmitter is also CE compliant; it exceeds US and meets European standards from EMI/EMC.

The MR Transmitters provide voltage (0-5 VDC and 0-10 VDC) and current loop (4-20 mA) outputs, allowing for easy electronic integration. Optional remote display and signal processors are also available from Hedland.

The F6700/F6750 Series Digital Display with integrated signal processor capabilities is offered to enhance the utility of the MR Flow Transmitters. In addition to remote flow monitoring, this unit can be configured to provide alarm processing and communication modes, including RS232, RS485, Modbus, Profibus and DeviceNet.
