Muco Industrie B.V. is a small Dutch based company, employing
6 people. Muco's core business is the development of micro-electronic
based products to client specifications, including HVAC equipment. Recently
Muco has developed, with their strategic partner Alusta, a flow sensor
for very low velocity up to 5m/sec. This is used in controlled natural
ventilation applications in commercial office buildings. Since natural
ventilation contributes to the reduction of energy consumption and can
improve the health of people, this market is expanding. In addition, from
year 2000 onwards standards for domestic houses will be increased, opening
additional market possibilities for self-controlled natural ventilation
Whilst the existing sensor could be used in these applications it has
performance limitations. These have to be improved to prevent a loss of
market share for the existing commercial market and to capitalise on the
new domestic market possibilities. The limitations of the existing hybrid
sensor relate to the mass of the sensor which in turn influences the temperature
of the environment and hence the accuracy of the sensor, especially around
zero-flow. It is also important that the sensor can measure reverse flow,
is not vulnerable to transport, and is reproducible.
The design of the new Silicon micro-machined sensor, based on MST-technology
will meet the future performance requirements. The project to develop
this took 22 months and cost 141.6 KECU. Additional investment to develop
the Home system for ventilation in domestic houses will be about 416 KECU
including costs of industrialisation and marketing. The product will be
put on to test-markets in mid 1999. Due to the lead time of the market
introducing a new product and because of legislation sales will take up
from 2001onwards The pay-back period will be 24 months and the ROI will
be approximately 2 assuming a 3 year product life cycle.
The new flow sensor is unique in terms of its performance over the velocity
range (0-5 m/sec) so it is expected that it can be exploited in many other
market areas. The layout for this will be patented. In addition, aerodynamic
testing tools for the sensor and product which were developed during the
AE have potential applications, and will be patented.
Muco found that a good agreement with your subcontractor is the basis
for a good night's rest, but a human fit is as important as a contract.
New grounds had to be covered with this sensor. With good project management,
co-operation with a subcontractor having an academic background can be
successful. Gaining in-depth knowledge of the world of your strategic
partner and your subcontractor is a key success factor.
Product development based on flow sensors asks for a multi-disciplinary
approach with regard to chip design, mounting requirements, aerodynamics,
testing, fine mechanics, end user market size and design for assembly
