GENERAL INFORMATION, SPECIFICATIONS, FEATURES GENERAL INFORMATION The TX80-Series are insertion turbine meters designed for use in 1-1/2" to 8" pipe. High-quality jewel bearings and precision shafts ensure long life and low friction. Available in 316 stainless steel, brass and PVC, sensor bodies are machined from solid rod for maximum low-flow performance. The TX80-Series use special fittings that ensure ease of installation and correct depth setting in the pipe.
INSTALLATION DISTORTED FLOWS Distorted flow profile tings (size 3” and above) require a hole to be cut in the pipe. The recommended hole size is 1-3/4”. Faster flow causes meter to read high FLOW 10X Diameter Minimum (See Below) Fitting Installation. TX80-Series meters require special fittings. The meter fitting must first be installed in the pipeline.

INSTALLATION FULL PIPE RECOMMENDATIONS Better Installation: Ensures full pipe Possible Problem: Allows air pockets to form at sensor Possible Problem: Post-valve cavitation can create air pocket Better Installation: Keeps pipe full at sensor Possible Problem: Air can be trapped Better Installation: Allows air to bleed off Caution: These flow sensors are not recommended for installation downstream of the boiler feedwater pump where installation fault may expose the flow sensor to boiler pressure and t
CONNECTIONS DIAGRAMS FT415 Standard Connections Electronic Metering Pump Battery Type: Lithium "C, 3V, replaceable PULSE SCALED Caution: Do not apply external power to the FT415.
OPERATION Modularity. Any of the TX80-Series flow sensors can have electronic modules mounted directly to them, either at the time of order or by adding an adaptor kit in the field (part number MK10). Alternatively, the flow sensor and indicator or transmitter can be installed remote from each other. The FT420 is an indicating transmitter (rate, total, 4-20 mA output), and the AO55 is a blind 4-20 mA transmitter. For data logging, add the DL76.
MAINTENANCE Caution: Never remove the u-clip retainer when the pipe is under pressure. Always remove pressure from the pipe before attempting to remove the meter. Removal under pressure may result in damage or serious injury. Rotor Replacement. It is unusual for a rotor to require replacement due to damage sustained in normal service. More commonly, the meter is dropped while it is out of the pipe. Another reason for rotor replacement is shaft wear after long service. Rotors are easily field-replaced.
