ALARM OPTIONS: 7430

Inductive Ring Sensor

7430 Series flowmeters with metallic
floats can be ordered with an inductive
ring sensor that is able to detect a
predetermined rate of flow and is
compatible with stainless steel or
Carboloy floats only.

Inductive ring sensors are 2-wire, DC, low
current devices and are designed to be
used with a remote intrinsic safety barrier
/switch isolator. Sensors are available
as either proximity or latching devices.
The sensor can be positioned to trigger
at any point on the scale. It is able to

7430 with Inductive
Ring Sensor

detect the metal float by producing an
electromagnetic field that senses the float
within its sensing zone.

OPTIONS

Alarm Fiber-Optic or

Inductive Ring Sensor

Certified Calibrations Conform to ISA RP 16.6

Scales Any volumetric unit

The inductive sensor connects to a
barrier/switch isolator which powers the
sensor and provides the desired switching
option. Barrier/switch isolators are
available with 220VAC, 110VAC or 24VDC
supply voltage requirements, contain
single pole double throw (SPDT) relays,
and are DIN rail mountable. See barrier/
switch isolator specifications for electrical
connections and further details.

Maximum operating temperature 40° C
for 1/8” float; 70° C for 1/4” float.

Note: We can supply the safety barriers/
switch isolators upon request. User must
provide the power supply voltage

Fiber Optic Sensor

The fiber optic alarm sensor is an available
option for all 7430 Series flowmeters
and is compatible with all float materials
except sapphire. The sensor is used to
detect a predetermined rate of flow.
The sensor can interface directly to a
Programmable Logic Controller (PLC) or
when connected to a separate relay can
trigger a local or remote alarm.

The fiber optic sensor is mounted in a
junction box attached to the side of the
flowmeter. The sensor uses a pair of
fiber optic cables, an emitter and
receiver, to transmit the light generated
by the sensor. Note: Maximum operating
temperature 131° F.
