Differential Cone Flow Meters

Contact Teltherm for technical assistance and quotes.

NuFlo Cone Meter has wide rangeability and operates over large turndowns which allows differential pressures to be measured down to < 1 inch water column. It generates a low noise differential pressure signal at the centre and back of the cone.

High Performance Characteristics:
Accuracies up to ± 0.5% of reading (Reynolds Number and fluid dependent) with a nominal repeatability of 0.1% under many conditions and modes of operation.
The meter can operate with turndowns nominally up to 10-1.
These specifications meet custody transfer performance requirements for natural gas transmission measurements with sizes to > 36 inches. Contact Teltherm for exact rangeability per process fluid.

Technical Flexibility:
Manufactured to order in diameters from 1 in. to 48 in with flanges ranging from Class 150 to 1500 in accordance with ASME B31.3. Available in special materials such as duplex stainless steel and hastelloy.

Oil and Gas: Upstream & Midstream Applications Include:
Natural Gas Custody Transfer Measurement (CTM), Wellhead and Separator Measurement (both produced water and gas) Compressor Control and Fuel Gas, Wet Gas and Steam,Natural Gas Allocation Metering, White Oil Blending, Seawater Pump Control, Crude Oil Pump Control, Allocation and Injection Metering (all forms), Enhanced Oil and Gas Recovery (CO2 and Steam), Coal Bed Methane (CBM) for low pressure systems (circa 5-20 psig), Pure Product Metering opportunities in refining applications.

Oil and Gas: Downstream applications include:
Gas Processing, Butane, O2, CO2, Liquid Natural Gas (LNG), Waste-Water, Municipal Water, Pharmaceutical.
