Compliance Note
One thing to flag for your compliance paperwork: this product is not RoHS-compliant. If your site or end customer has RoHS restrictions, that's a dealbreaker. REACH information is available per Article 33 requirements, so that part of the documentation chain is covered.
What It's For
This couplant is specifically for portable ultrasonic flowmeter setups — the kind where you clamp transducers onto existing pipe and take a spot measurement. Water-based and temporary means it washes off easily after the reading, so you're not leaving residue on stainless or carbon steel pipe. The -34 to +38 °C range means it stays viscous enough to work in cold weather but won't boil off on hot lines. If you're building out a SITRANS FS220 kit for field service, this is the consumable you need in the case.
