The input circuit (signal from initiator [20]) is monitored for broken wire and short circuit. An
error in the input circuit causes blocking of the output (signal to flow computer electronic me-
ter [12] and to the 3/2-way solenoid valve [21]). The electronic meter [12] is used together
with a mechanical measuring chamber for temperature compensated delivery of mineral oil
products.
The above mentioned time relay is required that fluctuations of the liquid level in the sensing
element causing measurement interruptions (closing of the shut-off valve) deactivate the
elec. meter (interruption of the power supply) not until a delay of at least 8-10 s. The reactiva-
tion of the elec. meter takes place without delay, as well as the interruption of the power sup-
ply to the above 3/2-way solenoid valve [21] and its reactivation.
