Note: In electrically noisy applications, ground the meter to the pipe where the transducers are
mounted to provide additional noise suppression. This approach is only effective with conductive
metal pipes. Remove the earth (chassis) ground derived from the line voltage power supply at the
meter and connect a new earth ground between the meter and the pipe being measured.
Note: The terminal blocks accomodate wire gauges up to 14 AWG.
Note: AC powered versions are protected by a field replaceable fuse. This fuse is equivalent to
Littelfuse/Wickmann P.N. 3720500041 or 37405000410.
DC Power Connections
The device can be operated from a 10 to 28 VDC source, as long as the source is
capable of supplying a minimum of 5 Watts of power.
Connect the DC power to 10 to 28 VDC In, Power Gnd., and Chassis Gnd., as in Figure
1.5.
