Abstract

PURPOSE: To make it possible to prevent the error in flow measurements, when a tube is not fully occupied, by mounting a level meter in either a flow meter transmitter tube or a connecting tube thereby to detect the liquid level.
CONSTITUTION: The flow detecting signals of a flow transmitter 1 are transmitted to a signal converter 5 so that they are indicated as a low rate in an indicator 6 through a relay contact 8. A liquid level detector 3 of conduction type is arranged at one end of a transmitter tube 2 of the flow transmitter 1 so that the output signals are fed to a electromagnetic relay 7, if the tube of the transmitter 1 is under non- full liquid condition, to block the input circuit of the indicator 6 by means of the relay contact 8 thereby to indicate that the flow rate is zero or that the transmitter tube 2 is under the non-full liquid condition. If the inside on the transmitter tube 2 restores the full liquid condition, the relay contact 8 is made, and the normal flow metering condition is restored.
