Nuflo Liquid Turbine Flow Meter NuFlo液體渦輪流量計
Accurate Flow Measurement
早在1957年，NuFlo公司就成功開發并推出了針對油田開發和生產的第一款渦輪流量計，此款流量計使用了碳化鎢硬質合金的軸承和支撐件，以滿足油田生產的苛刻要求。經過幾十年的現場使用和考驗，NuFlo公司的渦輪流量計在耐用性和測量精度等諸多方面的出色表現已獲得業界的廣泛認可，目前NuFlo渦輪流量計廣泛應用于各地。In 1957, the Nuflo liquid turbine flow meter was developed with a tungsten-carbide shaft and bearing to withstand the rugged conditions of the oil field. Over the years, it has earned an unsurpassed reputation for withstanding severe punishment while maintaining operational and measurement integrity. Today, it remains a bestseller among Cameron’s NuFlo liquid measurement products.

NuFlo液體渦輪流量精度
根據流量計的線性特征，NuFlo 渦輪流量計的精度有“標準級”和“工業級”兩個精度等級。標準精度流量計應可為測量精度要求不太高的場合提供更具性價比的解決方案；高精度等級的流量計應用于等級要求相對較高的場合。在一定流量范圍內，還可提供更高精度等級（高于0.5% ）的渦輪流量計。
精度等級 精度 重復性
標準級 ± 1% ± 0.5%
工業級 ± 0.05% ± 0.02%
NUFLO 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
Cameron 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 meters are equipped with slip-oflanges, 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-in. through 8-in. 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 maintenancefree operation of conventional NUFLO flowmeters 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-in. EZ-IN RF requires special centering rings.
1.Permanent conduit connection is standard.
2.ROTOR is pitched and pre-calibrated to determine accuracy.
3. END CONNECTIONS available, flanged or threaded, standard or special.
4.FLOW VANES increase performance at low rates.
5.FLOW VANE HUB supports rotor assembly.
6.ROTOR SHAFT, BEARINGS, AND THRUST BALL are made of tungsten carbide for long service without lubrication other than by the liquid being measured.
7.RETAINING RINGS make disassembly easy.
8.FLOWMETER BODY is sturdy, one-piece construction, precision finished.
WECO 1502 Union End Connection
Flowmeters with 1502 end connections are commonly used in high-pressure oilwell service applications. Meter sizes 1”, 11/2” 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 1502 union end meters have two pickup adapters.
Applications
Cameron offers turbine flowmeters in a variety of end connections and accuracy levels. Typical applications are:
- Water-injection measurement
- Heater treaters
- Test and production separators
- Disposal wells
- CO2 injection
- Steam generator fuel and feed water
- Metering liquid fertilizer
- Water, fuel, and chemical measurement in plant settings
- Chemical tank loading and unloading
- Measuring liquid propane
- Insitu mining and leaching

Accuracy
NuFlo meters are classified as Standard Grade and Industrial Grade, based on the linearity of the meter. The Standard Grade meter provides a cost effective measurement solution for applications where higher accuracy is not required. For higher accuracy applications, an Industrial Grade meter can be used. Such meters can achieve even greater accuracy if the range of the flow through the meter is specified.
CAMERON Liquid Turbine Meters
