Accurate, Heavy Duty Sensors that offer Exceptional Value.
Truflo Sensors Measure liquid Flow Rates in Full Pipes.
The wetted materials are PFA, Ceramic and PP, PVDF
making this model highly versatile and chemically
compatible with many liquid process solutions.
Sensors can be installed (½ to 24 in.) pipes using
Truflo extensive line of custom fittings.
These fittings, include Tees, Saddles, and
Weldolets, and Align and Position the sensor to the
Proper Insertion depth Providing Accurate Flow
Measurement.
Remember to Lubricate O-Rings (Grease Supplied) Use an Alternating Twisting Motion
when Carefully inserting Sensor into Fitting (Grease
Included).
Remember this is an Instrument + Handle With Care
Advantages LS & LSS Models :

Rotor Replacement Procedure
To remove the rotor, insert a small screwdriver between the
rotor and the ear of the sensor.
Carefully Twist the screwdriver blade to flex the ear outward
enough to remove one end of the rotor and pin.
DO NOT flex the ear any more than necessary! If it breaks, the
sensor cannot be repaired and will not be considered as a valid
warranty claim.
Install the new rotor by inserting one tip of the pin into the
hole, then Carefully flex the opposite ear back enough to slip
rotor into place.
Lubricate O-rings with a Viscous Lubricant
(grease) compatible with the system. Very
Important (Grease Enclosed)
Using an Alternating/Twisting Motion, Carefully
lower the sensor into the fitting. Do Not Force
Engage one thread of the sensor cap then turn the
sensor until the alignment tab is seated in the
fitting notch (Fig-1) Ensure Tab is Parallel to Flow
Direction.
Ensure Tab / Notch are Parallel to Flow Direction

Hand Tighten the Sensor Cap. DO NOT use
any tools on the sensor cap or the cap threads

Press to select 4-20mA output for Flow Rate or Flow Total.
Pressto adjust A/O low scale to correspond to the display value (programmable).
Ex: A/O is 4-20mA the display is 0 to output 4mA, this value must be set for 0
Pressto adjust A/O hi scale to correspond to the display value (programmable).
Ex: A/O is 4-20mA, the display is 90.0 to output 20mA, this value must be set for 90.0
Press to select adjusting For Valves Above Flow Rate, press to modify the A/O zero.
PS: Use this function to adjust the real A/O zero. i.e. If you wish to have 0mA read other than 0 i.e. 10 GPM
Press to select adjusting flow rate, press to modify the A/O span.
PS: To use this function to adjust the real A/O span.
