Turbo-FloTM probes offer the precision of turbine technology with rugged construction. The practical design of the probe includes a bluff bar which protects the turbine from foreign materials in the stream as well as from over insertion. Installation is simple and does not require special fittings. The Turbo-FlTM probe may be installed in standard pipe tees, through pipe saddles, welding spuds and 1 1/2” full opening ball or gate valves.
- 303/304 stainless steel housing construction.
- Probe lengths from 6 to 54 inches for use in pipe sizes as large as 72 inches in diameter.
- Maximum operating pressure of 400 psig.
- Adjustable insertion length for your pipe size.
- Rugged construction for industrial environments.
- No external power required.
- Wide measuring range with 30:1 turndown.
- Low mass Delrin® turbines offer improved sensitivity and long life.
- Use standard pipe fittings for installation.
The turbine is positioned in the mid-section of the pipe with its axis of rotation parallel with the flow stream. Fluid velocity causes the turbine, which has a ring magnet inside of its hub, to rotate in proportion to flow rate. As the turbine rotates, the magnetic field passes through a coil in the probe body, generating a pulse output in proportion to the turbine rotation speed. Flow volume is then determined from fluid velocity measurement and pipe diameter information.
The TF-10000 Insertion handle facilitates installation in low pressure systems. (25 psig maximum)
Probe mounted options include 4-20 mA signal output transmitters and displays. The LCD rate/total display does not require external power. Turbine rotation recharges the lithium power cell in the display.
Transmitters and displays can also be wall mounted. Shown: TF-15350-2 Rate/total display; TF-15390 Rate/total display with 4-20 mA transmitter; TF-15385 4-20 mA transmitter (no display)
The wall mounted TF-15275 Series of Flow Controllers includes 4-20 mA signal output and two optional adjustable set points each with Form C 5A contacts. NEMA 4X enclosure. 85-265 VAC, 47-63 Hz.
