Can a metering pump measure automatically?
Thread Content
For example, when I start the metering pump, it pumps a specified amount of material into the container and then stops automatically. There’s no need to install anything on the pipes; the metering pump itself can handle this, right?
The metering pump can adjust its stroke to control the flow rate, and it is equipped with scales. But it cannot accumulate on its own; external timing assistance is required
A single metering pump alone cannot achieve this goal; it requires a means of monitoring, such as level detection or weight measurement, as well as a control system, such as a PLC, DCS, or digital display, to control the start and stop of the metering pump. Alternatively, a level switch can be installed on the container; when the liquid level reaches a specified value, the relay will change its output from on to off or from off to on, which is then connected to the motor circuit of the metering pump in order to stop the metering pump.
Or add a time relay to turn off the pump after a certain period of time once it has started running. A metering pump can control the flow rate; by multiplying this by time, the amount of material added can be determined.
This works; it’s probably the simplest method
A metering pump can send signals as well as receive them. The signal emitted represents the flow rate passing through the metering pump ； Receives signals to change the flow rate through the metering pump. The metering pump itself does not have the function of automatically adjusting flow rate.
It is generally used for adjustment; few people use it for measurement.
It’s not feasible; a signal from the backend is required to be sent to the metering pump, as the metering pump does not have the capability for precise measurement
