Nuflo Liquid Turbine Flow Meter NuFlo液体涡轮流量计
Accurate Flow Measurement
早在1957年，NuFlo公司就成功开发并推出了针对油田开发和生产的第一款涡轮流量计，此款流量计使用了碳化钨硬质合金的轴承和支撑件，以满足油田生产的苛刻要求。经过几十年的现场使用和考验，NuFlo公司的涡轮流量计在耐用性和测量精度等诸多方面的出色表现已获得业界的广泛认可，目前NuFlo涡轮流量计广泛应用于各地。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液体涡轮流量精度
根据流量计的线性特征，NuFlo 涡轮流量计的精度有“标准级”和“工业级”两个精度等级。标准精度流量计应可为测量精度要求不太高的场合提供更具性价比的解决方案；高精度等级的流量计应用于等级要求相对较高的场合。在一定流量范围内，还可提供更高精度等级（高于0.5% ）的涡轮流量计。
精度等级 精度 重复性
标准级 ± 1% ± 0.5%
工业级 ± 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:

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
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.
