We developed our first flowmeter for oilfield applications in 1957. The meter incorporated a tungsten-carbide shaft and bearing to withstand the rugged conditions of the oilfield environment. Over the years, this flow meter has built an unsurpassed reputation for withstanding severe punishment while maintaining operational and measurement integrity. 

NUFLO LT standard piping liquid turbine flowmeters indicate flow rate and measure total throughput of a liquid line. As liquid flows through the meter and over the rotor, the rotor turns at a speed that is directly proportional to the flow rate. A magnetic pickup senses the rotor blades as they pass and generates an electrical (sine wave) signal. These electrical pulses are then transmitted to the flow measurement readout equipment.


End connections

Sensia offers turbine flowmeters in a variety of end connections and accuracy levels. Typical applications are:

  • Threaded
  • Grooved
  • Flanged
  • EZ-IN
  • WECO 1502
Flanged End Connection

Turbine flowmeters with flanged end connections are available in both raised-face (RF) models and ring-type joint (RTJ) models. Flanged materials can be carbon steel or stainless steel. All flanged NUFLO liquid turbine flowmeters are equipped with slip-on flanges, which are then welded to the outside of the meter rather than being welded to the end of the meter body. Thus, the flange never comes into contact with the fluid being measured. The flanges are designed to mate with ANSI B16.5 flanges.

Grooved End Connection

Flowmeters with grooved end connections are available in 7/8" through 8" sizes.

EZ-IN End Connection

Series BF turbine flowmeters with EZ-IN connections provide a cost-effective alternative to typical flanged-meter applications. Series BF meters with EZ-IN connections offer the accuracy, rugged construction, and maintenance-free operation of conventional NUFLO flow meters plus the following advantages:

  • Lower installation cost
  • Less expensive than a conventional, flanged meter
  • Spreader nuts enable easy removal and inspection
  • The raised-face EZ-IN meter will mate to any flange rated ANSI 150# to 1500#. The ring-joint (RTJ) version will mate to ANSI 900#, 1500# or 2500# RTJ flange (specify flange type when ordering)
  • CE-marked 8" x 8" EZ-IN RF requires special centering rings
WECO 1502 Union End Connection

Flowmeters with 1502 end connections are commonly used in high-pressure oilwell service applications. Meter sizes 1”, 1-1/2” and 2” have 2” union end connections with a wing nut on one end and thread on the other end. The 3" meters have 3" union end connections with the option of a wing nut on one end and thread on the other, or threads on both ends. All NUFLO WECO 1502 union end meters have two pickup adapters.
