  • Page 3 Introduction The Safmag β-meter provides cost effective measurement of flowrate in applications where mechanical flowmeters are traditionally utilized. The design concept has focused on simplicity, whilst retaining all benefits associated with the use of an electromagnetic flowmeter. The β-meter comprises a flowtube sensor and a display unit which is mounted remote from the sensor.
  • Page 4 Installation guides Remote Electronics The remote electronics display may be mounted up to 100 metres from the meter body using SAFMAG cable. It should be mounted on the wall or a pipe stand. The display housings have dedicated points for mounting. DO NOT drill into the enclosure, this will void IP rating and warranty.

  • Page 5: Application Guidelines

    Meter Body The flowmeter should be lifted by a rope sling being passed around the outside of the meter or, in the case of the large meters the lifting lugs should be used. Never pass a cable or beam through the flowtube for lifting purposes, as this will damage the flowtube liner and render the meter unusable.

  • Page 7: Installation

    Safmag Magprobe (Insertion mag) Flow rate = ( 0 – 6 m/s ) / ( 0 – 18 ft/s ) The insertion probe must only be installed with the flow in the direction of the arrow marking. The alignment of the probe is important for accurate flow measurement, and care should be taken to ensure that the point indicator on the terminal box mounting plate points along the axis of the pipe.

    General The β-meter display/signal converter allows a fast response time for the sensors ≤150NB. This is achieved by automatically selecting higher coil frequencies permitting faster update times for flow calculations. These features allow batching of small volumes and ensure an acceptable accuracy. Size 50Hz Power Supply 60Hz Power Supply...

  • Page 19: Control Functions

    MODBUS RTU (Optional) The β-meter uses the MODBUS RTU protocol. This protocol defines a message structure that hosts and clients will recognize and use on the network over which they communicate. The MODBUS RTU uses a Master-Slave Query-Response Cycle in which the signal converter is the slave device.
