Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open. • Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case. tape Micro Motion T-Series... - Page 17 • If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so that the purge gas will displace air from bottom to top. • If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so that the purge gas will displace air from top to bottom.
