M ax error < 0.2 % o f rate, typical 0.1% of rate (1:1
to 10:1)
power supply: 8 to 40 VDC, less than 1.6VA, surge and
reverse polarity protection
isolated no polarity programmable pulse or flow switch
output, standard
programmable output pulse rate up to 500 Hz
programmable digital filter - our proprietary adaptive self
adjusting digital filter or a choice of a few others
isolated 4-20 mA, 12 bit, 0.05% output, option
isolated 0 - 5V, 12 bit, 0.05% output, option
isolated RS485 MODBUS, option
empty pipe detection
self cleaning electrodes
very small size
die cast aluminum NEMA-4X housing
blue tooth options
isolated USB option
the magmeter precisely measures highly pulsating and
interrupted flow
the GMAG100 magmeter has a very fast response
all outputs scaled and programmable
no moving parts
through the MODBUS you can configure any parameter,
read the flow rate and other variables
you can connect the GMAG100 magmeter to a MODBUS
RS485 2 wire network and it takes 1/8 load only which
allows to have up to 247 devices on the same network.
the RS485 is isolated and does not need external power
