1. GENERAL
The FS10 Series is a universal flow monitor and switch specifically designed for gas and liquid process analyzer sampling systems, and general flow
and level applications. The FS10A installs easily into a standard tube tee fitting or SP76 (NeSSI) modular manifold and uses a fast responding, highly
repeatable sensor. The FS10i is an insertion type instrument with ¼-inch or ½-inch NPT fitting (fixed 2- or 4-inch length) or ½-inch NPT compression
fitting (6-inch length, Teflon or stainless steel ferrule).

Technical Specications

FS10 Series INSTALLATION
Fluid Components International LLC 3
2. INSTALLATION
The FS10 is marked with a flow direction arrow or “A” etched onto the sensor element. It is located on the flattened area of the sensor body
close to the housing or on the assembled tee. For 1/4 and 3/8 inch tube tees, mount the instrument with the “A” upstream of the flow to maximize
sensitivity at low flow rates (flow into the “A”). Larger line sizes should follow the flow arrow direction. Refer to Figure 1. Where the flow tube is
not included with the sensor assembly, the orientation mark must be parallel to flow (±3°). For liquid vertical flows in particular, FCI recommends
the sensor element be installed where flow is in the up direction. In vertical low flow gas applications, flow in the down direction is
recommended.
As a level device, the orientation mark can be perpendicular or parallel to the liquid level. The sensor element may be installed top mount 90° to the
liquid surface. The sensor element can be at any angle as long as the flow direction follows the flow arrow. For liquid applications where the flow
element is positioned other than horizontally, FCI recommends the flow go in the up direction.
Caution : To minimize the possibility of damage, leave the protective covers over the sensing area in place until the time of installation.
Take extra precaution with the sensing elements and surface when installing.
For NPT process connections: Apply the appropriate sealant compatible with the process media to the male threads. Tighten until the orientation
mark is positioned correctly. Check for leaks.
Note : ATEX/IEC labeled units are supplied with a UV filter disc located inside the silicone boot. The disc can be removed if the dis-
play is not subjected to UV light (e.g., sunlight, mercury-vapor lighting, etc.). See “Figure 16 – Installation Dimensions, FS10
Silicone Boot and UV Filter” on page 16 for UV filter disc removal details.
Special Conditions for Safe Use
1. Provisions shall be made to prevent the rated voltage being exceeded by transient disturbances of more than 40%.
2. For applications in explosive atmospheres caused by air/dust mixtures, cable and conduit entries used shall provide a degree of ingress
protection of at least IP 54 according to EN 60529.
3. When the temperature under rated conditions exceeds 158 °F [70 °C] at the cable or conduit entry point, or 176 °F [80 °C] at the branch-
ing point of the conductors, the temperature specification of the selected cable shall be in compliance with the actual measured tempera-
ture.
4. Cable gland assemblies are factory tightened – do not adjust; M12 connectors assembled finger-tight. Mencom MDC-8MR-PG9 or equal
M12 connector is used on FS10.
5. Parts of the enclosure are non-conducting and exceed the maximum permissible resistance according to IEC 60079-0. Therefore, to avoid
electrostatic charge build-up, do not rub with a dry cloth or clean with solvents when the instrument is installed/used within a potentially
explosive atmosphere.

Instrument Wiring
Only qualified personnel are to wire or test this instrument. The operator assumes all responsibilities for safe practices while wiring or troubleshoot-
ing. One of the following wiring instruction and diagrams illustrate the requirements for power input, alarm and analog outputs and safety instruc-
tions for the unit being installed.
Caution: The instrument contains electrostatic discharge (ESD) sensitive devices. Use standard ESD precautions when handling the
instrument.
Recommended Minimum Wire Gauge
The following wire gauge chart specifies the correct wire for the distance to the power source or loads. For best results from the open collec-
tor output, use shielded cable (50 ft. max.) and route it separately from the power source or relay load.

Grounding
Properly connect the switch to earth ground for safety and operational reasons.
The circuit board is tied to the enclosure case internally and both are tied to the probe assembly. If the installation pipe or vessel is not prop-
erly grounded, connection to earth ground may be connected at the output connector, i.e. M12 or cable pigtail. Use the recommended wire
gauge specified for the input power and distance listed in the chart above. Do not connect the earth ground to DC ground (terminals
are marked “GND”, "RTN", “COM” or “–”).
Input Power, 24 VDC
FCI recommends installing an input power disconnect and a fuse near the instrument to interrupt power during installation, maintenance,
calibration, alarm selection and troubleshooting procedures. Install conduit according to the local electrical codes or hazardous location
requirements.
Attach the power leads according to the Input/Output connection schematic on the following page. If the unit has an M12 interface, verify
that the mating connector pin numbers match the designations of the wiring diagram. If the unit is supplied with a cable pigtail, connect the
flying leads via an approved terminal block or connector in an electrically safe and approved conduit box.
Attach the wires to the relay and other functions as needed. The relay contact conditions are shown in the alarm state (de-energized). The relay’s
maximum rating is 1 A @ 24 VDC/120 VAC (FM only), 24 VDC (ATEX), resistive loads.
Refer to “3. OPERATION” on page 23 for details on setpoint and alarm state settings.

Caution: Instrument power is provided to Pin 1 of the I/O connector/cable (white wire). To avoid equipment damage always be sure
that power is connected to Pin 1 (white wire) when making external I/O cable connections. Do NOT apply power to Pin 8 (red
wire) or any other pin other than Pin 1.

Switching Inductive Loads
If the FS10A/FS10i relay contacts are to be used to energize or de-energize an external relay, diode suppression must be used across the external
relay coil. Use the guidelines in the following example to select the proper diode.
A Tyco Electronics relay K10P-11D15-24 is used as a slave relay. The DC coil voltage is specified at 24 VDC and the specification indicates a coil
resistance of 650 Ω. The DC coil current is calculated by dividing the rated coil power by the rated voltage VDC or dividing the rated voltage VDC by
the coil resistance. In this case the current through the coil will be around 37 mA (24 ÷ 650). Refer to the K10P-11D15-24 data sheet.
It is recommended the diode reverse voltage (Vr) rating be twice or greater the voltage across the relay and the diode forward current (IF) rating be
greater than the relay current. Diodes 1N914 or 1N4148 meet these limits for this case.

A schematic view of the FS10 output modes and corresponding jumper settings are shown below.
