Answers to common questions before buying equipment
Can the 12V/24V dosing controllers also be used stationary?
Yes.For stationary use, however, a sufficiently sized power supply is required, small battery chargers are usually undersized for this. If a undersized power supply is used, then experience shows that voltage drops occur during motor startup. As a result of this the metering device will shut down and the metering process is interrupted. Now the voltage of the power supply reaches its normal value, the metering device starts again and the user is facing constant inexplicable dosing termination.
Flowmeter selection: Which flowmeter turbine sizes are recommended for which flow rates?
To get the best results from measurement and control, the correct selection of a suitable flow meter for the desired flow range is important. On the one hand a flowmeter itself has only a limited workspace, on the other hand, for a good flow control at least four pulse per second of the flowmeter are necessary. From the series FHK / FHKU of the company Digmesa, which is distributed by us, flowmeter turbines with nozzle diameters of 1,0 ... 7,0mm are well available. The usable measuring ranges are:
|Digmesa flowmeter nozzle diameter||Value of flowmeter for water (pulse/l)||max. flow output (l/h)||min. flow output (l/h)|
