MAG FLOW Measurement

MAG888 Electromagnetic Flow Metering

Spire Metering brings state of art electromagnetic technology to meet your flow control requirements. Designed for measuring a variety of minimally conductive (5 µS/cm) fluids over a wide temperature range, MAG888 delivers the highest degree of accuracy and repeatability to your project. Options for integral or remote flow transmitter, NEMA 4X or submersible flow tube, Full Bore or Insertion design, 90-240 VAC/24 VDC or battery power make MAG888 the versatile choice for all you flow measurement needs. Analog, digital, alarm and serial outputs are STANDARD with every meter, with HART, Modbus, BACnet and M-Bus communications protocols available for seamless integration.
