Teledyne API Model M201E NH3 Analyzer Operator Manual

Maintenance Schedule

4.4AUTOZERO FLOW CHECK

Since the M201E is an ammonia analyzer, the flow through the AutoZero orifice is especially important. Check the AutoZero flow as follows:

1.This procedure should be performed with the sample pump running.

2.Remove the top cover of the analyzer. Locate the vacuum manifold at the center rear of the chassis. Locate the 1/8” tube fitting located on the very left side, as viewed from the rear of the analyzer. It will have a label of “0.010” indicating the flow orifice installed.

3.Remove the fitting and attach a calibrated flowmeter to the block fitting capable of measuring in the range of 500 cc/min. The flowmeter should indicate a flow of 500 cc/min ±10%.

4.If the flow is outside this range (most likely lower, due to plugging):

1.Turn off the sample pump and instrument.

2.Remove the 1/8” pipe-to-tube fitting and remove the ¼” sintered filter (p/n FL0000001). This filter is meant to protect the orifice; it will usually become plugged and need replacement rather than the orifice. Replace the filter, and then re-assemble the manifold. Restart the sample pump and recheck the flow.
