The model FLC-EM is a portable field verificator for checking magnetic-inductive flow meters. The measured values of the signal converter are captured and transmitted via an RS485 interface. The excitation current is measured and the settings of the signal converter can be stored as a reference for later tests or adjustments. The field verificator checks the functionality of the sensor, calibrates the 4 … 20 mA output and tests the input and output by means of a special motherboard.
Operation in the field
The FLC-EM is housed in a shatterproof, waterproof and shock-resistant service case. The field verificator is powered with high voltage AC 110 … 240 V and a nickel-metal hydride (Ni-MH) rechargeable battery in a separate circuit. Through verifying the performance of the measuring instrument, downtimes can be reduced and the high measurement accuracy can be guaranteed.
The instrumentation of the field verificator is protected by a plastic service case. The connections for current and wiring are located on an aluminium plate within the service case. Connections for an electronic motherboard and a notebook, the battery, the USB hub, as well as the necessary cables are also built-in.
