QuadraTherm® 640i/780i Now With Full Suite of Global Agency Approvals-cFMus, ATEX and IECEx

Press release date: March 12, 2014

Hazardous-Environment Flowmeters for Facilities Management, Chemical Processing, Oil & Gas, WasteWater, and Natural Gas Measurement

MONTEREY, CA – Sierra Instruments, a leading global mass flow meter manufacturer, is pleased to announce its evolutionary QuadraTherm® 640i/780i has received global approvals for the following standards of safe operation in potentially hazardous environments: cFMus (USA and Canada), ATEX (European Union) and IECEx (International). This signifies that the QuadraTherm is certified as flame-proof and protected from dust ignition sources and meets all design criteria for electrically-powered flow meters used in areas where combustible gases may be present.

The IECEx and ATEX certification programs ensure explosion-proof and hazardous area compliance in the European Union and international destinations. The cFMus certification program ensures explosion-proof and hazardous area compliance in the United States and Canada. With approvals, QuadraTherm is approved for applications in hazardous plant areas like facilities management, chemical processing, oil & gas, wastewater, and natural gas throughout the European Union and international communities.

"We designed and tested the QuadraTherm for safe operation in heavy industrial applications. The global approvals are a recognition that years of hard work in design and testing were right on target. Now our customers can use the QuadraTherm in even more heavy industrial application across the globe," says Scott Rouse, Product Line Director.

The QuadraTherm thermal mass flow meter's approvals are as follows:
cFMus
Class I, Division 1, Groups B,C, and D
Process Temperature Range: -40°C to 200°C (-40°F to 392°F)
T3C Ta = -40°C to 60°C (-40°F to 140°F)
Type 4x
ATEX and IECEx Approvals
II 2 G Ex d IIC T3 Gb
II 2 D Ex tb IIIC T200°C Db
Ta = -20°C to 60°C (-4°F to 140°F)
Process Temperature Range: -40°C to 200°C (-40°F to 392°F)

With these global approvals, Sierra's QuadraTherm can be used throughout the world where hazardous or explosive environments may be present, expanding the market for our customers.

The QuadraTherm provides the best accuracy +/- 0.5% of reading above 50% of full scale for flow meter air measurement and other gases; inline version with built-in flow conditioning; multivariable outputs, flow ranges up to 60,000 sfpm (305 smps), qTherm™ Dial-A-Gas®, Dial-A-Pipe™, and Hazardous Area approvals. The QuadraTherm is available in two models: the 640i insertion and 780i inline. The QuadraTherm family has a no-drift sensor with lifetime warranty; has multivariable output: mass flow, temperature, pressure (optional); measures all inert and all non-condensing clean gases; flammable gases (methane, propane, hydrogen, and digester gas); repeatability for mass flow rate is +/- 0.15% ; ValidCal™ Diagnostics to validate calibration in the field; and gas accuracy is +/- 1°C (1.8°F).
