RELIABILITY EVALUATION OF A BRAKE PIPE FLOW INDICATOR FOR USE WITH REMOTE CONTROL LOCOMOTIVE EQUIPMENT
The test data presented in this report show that the Type "B" Brake Pipe Flow Indicator is mechanically capable of operating one million cycles under laboratory conditions without failure or loss of sensitivity. Under prolonged exposure to high temperatures the diaphragm showed some effects of heat aging which is to be expected with molded rubber products not specifically synthesized to withstand high temperature environments. The apparatus developed for the cycling tests was realistic in terms of simulating a number of significant operating parameters of a flow meter used on locomotives in service. It appears therefore that the flow rater as used for a control function in remote-controlled locomotives is functionally adequate and no special precautions need be considered in relation to normally testing and maintaining this part.
