1. CAUTION The use of rubber gaskets and a lower fastening torque is not recommended and can cause insufficient surface pressure between the lining and the grounding ring resulting in leakage CAUTION Insufficient grounding can cause output fluctuations instability of the zero point or output drift Secure single point grounding with a grounding resistance of 100 Q or less is recommended Do not ground a welder to the detector to avoid damaging the detector Model MGG18 MagneW 3000 PLUS Smart Electromagnetic Flowmeter Detector Table of Contents Chapter 1 Introduction 1 1 1 2 1 3 Principle ot op ration a4v8asasvesarkedse tate sled mais dyads 1 1 System operation zeke beak eee hea inten eee 1 2 T 2 T Integral BY OG vu jane feka adr okekebkidetdk he dpek akta 1 2 12 2 10010 KE EE EE A a deceate 1 3 Man COMPorenNtS samaagdkesd nad datddkunaietaruatbinedutene siv 1 3 1 31 M ler type detector srona iaie ie E E dende trata erence bee 1 4 1 3 2 Flange type detector ss sssssisrrssissrsniuesedserreseetssesrecitrrtnnrtrrnnrNE cones ceanenncecbscennyearey 1 5 1 3 3 Union Hose Clamp type detector ccccccccececcceeeeeeeeeeeeeeeeeeeeeeeeeeeeteeeeeeteeenes 1 6 1 3 4 Sanitary type detector a scien seveeses ocessennlvesunn ta keel eoemeanenpnevaseh cbethacwbeesemeeeennsecuet 1 7 123 5 Detector terminal VOX mpira ia ara ena anaa Aea Eaa dtn atdet 1 8 1 3 6 Approval of this device cc
