MFSM-L

MFSM-L water meters
Multi jet water meter MFSM-L for domestic water consumption with MID homologation certified by the Spanish Metrological Centre (CEM).

MFSM-L water meter is manufactured in copper alloy body and includes a pulse output pre-equipment. Straight sections are not necessary at the MFSM-L water meter input or output U0-D0.
Ratio accuracy R80.

MFSM-L water meters ranges from DN 32 to DN 50.

– Copper alloy body coated with Epoxy paint.
– Turbine and dial in thermoplastic material.
– Vacuum dial to prevent condensation of water.
– Magnetic transmission protected against external magnetic fields.
– Pre-installation of pulser for remote reading. Quick connection without stopping or dismantling the meter.
– High mechanical and wear resistance.
– MID approval for potable water. MID 2014/32 / EU Directive.
– Straight sections are not necessary at the Hidrojet input or output U0-D0.

1- Which is the difference between dry dial, wet dial and semi-dry water meter dial?
On water meters with dry dial the reading mechanism (clock) is tightly separated from the wet chamber of the meter.
On Wet dial water meter the watch is totally immersed in the fluid.
For water meters with semi-dry dial, the reading mechanism is totally immersed in the fluid but the dial is partially serrated and protected by a sealed capsule.

2- What are the ranges of measurement and precision?
The measuring range of the meters is determined by the Directive MID 2014/32 / UE establishing the ratio between the value of the permanent flow (Q3) and that of the minimum flow (Q1). The water meter can measure up to the maximum flow rate (Q4) for short periods of time without deterioration.
The maximum permissible error, positive or negative, in volumes between the transition flow (Q2) (included) and the overload flow (Q4) would be 2% with a water temperature ≤ 30 ° C.
The maximum permissible error, positive or negative, in volumes between the minimum flow rate (Q1) and the transition flow (Q2) (excluded) would be 5%.

3- The MID directive and its compliance
The MID Directive (2014/32 / EU Measuring Instruments Directive) is a directive of the European Union whose purpose is to harmonize the different aspects of Legal Metrology in the member states.
The most important aspect of this directive is that equipment in possession of a MID certificate can be used in the EU.

4- How should the single jet water meters be installed?
HIDROCONTA single jet counters do not require special installation conditions.
If you have any doubt about the installation of these equipments, it is recommended to follow the instructions indicated in the technical data sheet of the product.
