Technical Specifications
• Process Connection
3/4 inch male NPT standard. 1 inch BSP, 1 inch
male NPT, 1/4 inch male NPT (FLT93-F only),
flanged mounting, spool piece with 3/4 inch NPT tee
or retractable sensing element available.
• Insertion Length
Beginning as low as 0.9 inches (23 mm). Standard as
well as custom lengths are available.
• Sensing Element Material
All wetted surfaces are 316 Stainless steel, with all-
welded construction. Hastelloy C-276, Monel 400
and electro-polished stainless steel surface preparation
optionally available. Titanium is optionally available
on the FLT93-S configuration only.
• Operating Temperature
Control circuit:
Ambient: -40 to 140°F (-40 to 60°C).
Sensing element:
Standard temperature configuration:
-40 to 350°F (-40 to 177°C).
Medium temperature configuration:
-100 to 500°F (-73 to 260°C).
High temperature configuration:
-100 to 850°F (-73 to 454°C).
• Operating Pressure
Hydrostatically proof pressure tested to 3500 psi
(241.3 bar) at 70°F (21.1°C). De-rated with
temperature, the maximum recommended operation
service is 2350 psi (162 bar) at 500°F (260°C).
Higher ratings available with special construction and
test certification.
• Flow Range
From 0.01 to 5 fps (0.006 to 0.15mps) with fluid or
0.25 to 120 fps (0.076 to 38.1 mps) with gas,
depending upon model.
• Signal Output
Buffered voltage output available as a standard for
temperature and either flow or level/interface. The
minimum load impedance is 100 K ohms.
• Accuracy
Switch point accuracy:
Up to ± 2% of the switch point
velocity.
Monitoring accuracy:
±5 % reading (or ±0.04 fps, 0.012 mps,
which ever is larger for liquid applications
and ±2 fps, 0.061 mps, which ever is larger
for gas applications).
Level accuracy:
Down to ±0.1 inch (±0.25 cm)
Temperature accuracy:
Up to ±2 °F, (±1.1°C) depending upon
application. Higher accuracy is available
with factory calibration.
• Repeatability
