General:
Each portable Transit Time flow meter shall have the following design features and engineering specifications:
Performance specifications
The ultrasonic flow meter shall have an accuracy of ±1% of reading or 0.1 ft/sec (0.03 m/sec), whichever is greater. Have repeatability and linearity of ±0.25%.
Shall operate on clean liquids in full pipes with less than 2% solids or gas bubbles at flow velocities from ±0.07 to 39 ft/sec (±0.02 to 12 m/sec).
Operate on the following pipe materials: carbon steel, stainless steel, PVC, PVDF, fiberglass, galvanized steel, mild steel, ductile iron, glass, copper, brass and pipes with bonded liners including cement, epoxy, rubber and Teflon.
Operate on AC power or from internal, rechargeable batteries.

Transducers
The flow meter shall have a dual transmitting/receiving, clamp-on transducers operating at 1.28MHz.
The transducers shall operate continuously at temperatures from -40°F to 300°F (-40°C to 150°C).
The standard transducer pair shall be designed to install on pipes with nominal diameter ranging from 2" to 48" (50 mm to 1200 mm).
Have 12 ft (3.4 m) length coaxial cables from the electronics with BNC connectors to transducers.
Shall include manufacturer's recommended transducer coupling compound. Shall include stainless steel mounting hardware, pipe clamps and aluminum alignment bar.
Shall include BNC seal jackets for transducer operation in wet or submerged conditions
