What is the best matching word for the mode of operation of a pump doing injections into a pipe system?
By "injections", individual short feedings with no (temporal or other) relation to each other are meant. That mode is distinct from a "pulsed mode" where constantly are pulses generated.
Could one use "The pump operates injective." or "The pump is in injectional operation mode." to describe that mode of operation in contrast to a "continuous operation mode"?
Or should one better stick to the less precise term "non-continuous operation mode" in that case?
Thanks in advance!
To clarify what that modes of operation should stand for:
Setting the pump to "continuous operation mode" means to instruct the pump to produce an continuous output until it is told otherwise. While operating in that mode, the output level of the pump can be directly adjusted from 0 to 100%.
Setting the pump to "injectional operation mode" means to force the pump to produce no output until an external command instructs it to do so for a limited time from that moment on. In that mode, the configured output level of the pump comes into effect only while instructed to produce an output by the external command.
This question is aimed to find the suitable words that can be used to distinguish between these two modes of operation.
