• Product contact surfaces constructed of FDA approved materials designed in accordance with 3A and EHEDG standards.
• Sensor is CIP ⁄ SIP cleanable, and the sensor I.D. matches the process piping to eliminate hard-to-clean step changes.
• Available with a variety of sanitary process connections with easily accessed process gaskets to facilitate inspection and maintenance.
• Compact, all stainless steel meter body is fully-welded, and critical junctures are potted to provide a hermetic seal, protecting the internal components and wiring from pressurized steam, water and sanitation chemicals

The 8721 hygienic sensor is specifically designed for the demanding applications in food, beverage, and life sciences. The robust, all-welded, full diameter sensor is constructed of FDA approved materials that are fit for purpose, and is authorized to display the 3-A Symbol (Authorization #1222), is certified by EHEDG (#C03-5229) and is approved for use in FDA Grade A milk meter based timing loops (M-b 350). Sizes range from ½” (15mm) to 4” (100mm) and are available in a variety of industry standard process connections.

With a wide range of liner and electrode materials available, the Rosemount 8700 Series Magnetic Flowmeter family is suitable for virtually any conductive liquid application. Rosemount Magnetic Flowmeters offer the benefit of measuring flow in a package unaffected by density, temperature, pressure, and viscosity change.
 
Step 1: Flow Sensor Type

	Liner	Notes	Temp Limits	Type  and Line Sizes
	PFA	BEST FLUOROPOLYMER Excellent resistance to chemicals and abrasion. Suitable for any application.	-20 to 350°F (-29 to 177°C	Flange 15 - 350 mm 0.5 - 14 inch	Wafer 4 - 8 mm 0.15 - 0.3 inch
	PTFE	BETTER FLUOROPOLYMER More cost effective than PFA. Excellent chemical resistance, but less abrasion resistance than PFA.	-20 to 350°F (-29 to 177°C	Flanged 15 - 900 mm 0.5 - 36 inch	Wafer 15 - 200 mm 0.5 - 8 inch
	ETFE	GOOD FLUOROPOLYMER Similar chemical and abrasion resistance to PTFE, but a lower maxium temperature an more expensive.	-20 to 300°F (-29 to 149°C)	Flanged 15 - 400 mm 0.5 - 16 inch	Wafer 15 - 200 mm 0.5 - 8 inch
	Polyurethane	Typically applied to clean water (no chemicals). Abrasion resistant to slurries with small particles.	0 to 140°F (-18 to 60°C)	Flanged 15 - 900 mm 0.5 - 36 inch
	Neoprene	Typically applied to water and sea water. Abrasion resistant to slurries with small particles.	0 to 185°F (-18 to 85°C)	Flanged 80 - 1800 mm* 1.5 - 72 inch
	Linatex	Typically applied to mining slurries, abrasion resistant to larger debris.	0 to 158°F (-18 to 70°C)	Flanged 80 - 900 mm 1.5 - 36 inch

	Electrode Type	Application Notes
	Button	Standard electrode design. Use for most applications, especially where abrasion is a concern. Has fair resistance to coating which can be improved by properly sizing sensor.
	Bullet-nose	Use where coating is a concern and no solids are present. Bullet-nose electrode should not be used in abrasive or slurry applications as the particles will result in increased process noise on the electrodes.
Electrode Material		Application Notes
316L SST		Standard electrode material. Compatible with most low concentration water based applications. Avoid using stainless in higher concentration acid applications.
Nickel Alloy 276		Use in medium to high concentration acids where SST is not acceptable. Use in applications with high chloride concentrations, such as sea water.
Platinum (80% Platinum, 20% Iridium)		Ideal for liquor applications found in pulp and paper industry. Also ideal as a spare electrode option to cover nearly every application in a plant. Compatible with nearly every process fluid.
Tantalum		Ideal for high concentration acid flows such as hydrochloric and hydrofluoric acids.
Titanium		Ideal for high concentration caustic (base) applications such as sodium and potassium hydroxides.
