Description:
It is a multi-jet, wet, cold-water counter with the digit rollers and pionters - the EMI-SD water meter indicator wheel is installed in its own chamber, which is filled with a special protective liquid. because of the protected indicator, the water meter is the best measurement even in demanding conditions. Again, there is no water, so there are no suspended particles that could flow into the water meter dial. Therefore, EMI-SD water meters are always tested even in heavily polluted water or ice water. EMI-SDR is a remote communication system in combination remote readout.

Construction multi-jet wet dial meters
Our multi-jet turbine meters as wet dial model are characterised by the fact that the impeller shaft is connected directly with the register. The register’s rollers and pointers are surrounded by the measuring fluid. The advantage here is that the power transmission from the measuring chamber takes place directly in the register and thus, no friction losses occur. The result is a very low starting flow. In contrast to dry dial meters, this meter model cannot be influenced magnetically and metallic pollution cannot deposit itself on the impeller shaft or the coupling. We recommend this meter for all potable water qualities where pollution of the register through fine particles can be ruled out as far as possible
