Our company closely co-operates with metrology institutes and
normalising organisations in our country as well as abroad.
Permanent and very good co-operation is established with ÈMI in
Czech Republic, SMU in Slovakia as well as Goststandard in Russia
operating in Russian federation.

AUTHORISED METROLOGICAL CENTRE
Company MATTECH s.r.o. (Ltd.) has its own Authorised metrology
centre accredited to ensure metrologyl verifications of meter tubes
fitted with centric orifice plate, nozzle and Venturi tube. Our
authorisation is valid not only for verification of own production
line of meters (centric orifice plate, nozzles and Venturi tubes),
but for verifications of meters on basis of flow throttling with
valid Pattern approval of other domestic as well as foreign
producers. This way customers obtain primarily verified meter with
Document of verification. Activities and functioning of our AMS is
documented in AMS quality manual. In 2003 readiness of our AMS for
the entry of Czech Republic to EU was verified by ÈMI audit which
was crowned by new authorisation document.

Measurement with three-contact inside calliper |
With implementation of ISO 5167 standard in the
turn of 1992/93 Mattech’s flow meter was accredited with first
Pattern approval by SMU and subsequently by ÈMI – fluid flow meter
with throttling devices for flow measurement in the range dependent
on type of primary element from DN 50 to DN 1200. It is so called
pattern approval TSQ 142/93-001 valid in Slovak Republic and TCM
142/93-1631 valid in Czech Republic. During 1994-2000 these pattern
approvals were extended by two annexes on use of Venturi tubes and
individual centric orifice plates or nozzles. In 2003 Mattech
obtained ÈMI pattern approval for flow meter with segment orifice
plate for measurement of fluid flow with higher content of
impurities from DN to DN 500. During 2003 ISO 5167 standard was
revised and since 1st December 2003 it has been valid in current
version. Since then the production of new meters on basis of
throttling flow has been governed by this revised standard.

Measurement
in AMS |
The meter is verified by measuring geometric
dimensions of plate event. meter tube and piping sections in front
of and behind orifice plate. Validity of such verification is
defined by regulation no. 345/2002 Col. in valid version. In
compliance with particular pattern approval on the meter there is
placed metrology seal and meter identification. On request document
of verification can be issued. When validity of verification expires,
we are offering our customers further metrologyl verification on
meter with valid pattern approval on basis of throttling flow. If
the meter dimensions comply with ISO 5167, it would be given new
valid document of verification. If the meter does not comply, we
would issue document of rejection or after discussion with customer
we could make new plate event. the whole meter tube including new
verification. |
