seriesdedicated distributor●The existing 2-wire cable can be used as it is.

●The existing host system can be used as it is.

●Coriolis flowmeter ALTImass series can be used as it is.

●No restrictions on the compatible bore size and high cost performance.

●

Simultaneous 4 to 20 mA output and pulse output are possible.
Mechanical flowmeters (contact pulse output) that do not require a power
supply can be replaced with our Coriolis flowmeters.

●Cable cost can be reduced in the case of new installation.

Application example−CASE 1−At the consideration new installation of Coriolis flowmeter …
We want to adopt high-accuracy / high-reliability OVAL ALTImass series withabundant supply reference!, but ...
Long-distance cables need to be laid between the factory floor and the host system.
Cables are steeping price rise, so we want to use a 2-wire system...
ALTImass series (with output) requires at least a 3-wire cable...

With a 2-wire system, only analog signals (instantaneous flow rate) can be obtained.
If possible, I would also like a real-time pulse signal...

You can use a 2-wire cable!
The installation cost can be reduced!

Please leave it to OVAL 2-wire solution!

• Even 2-wire transmission can obtain pulse signal and upper / lower limit alarm signal!
• ALTImass series is high-accuracy and high-reliability because it has abundant
supply reference!
◉ The cost can be reduced by adopting a 2-wire cable for the long-distance laying cable between the field and the host system.
◉ A dedicated distributor provides general-purpose analog and also pulse outputs.
It is also possible to manage integrated flow in real-time, which is difficult to handle with a general "2-wire dedicatedCoriolis flowmeter".
◉ It can also handle "large bore" applications that cannot be handled with general "2-wire dedicated Coriolis flowmeter".
◉ Instead of "2-wire dedicated Coriolis", the proven, high-performance, and reliable "ALTImass series" can be used.

◉This instrument allows 2-wire cable Coriolis flowmeters to be upgraded to the ALTImass series without having tore-lay the cables.
◉It can also be used for "large bore" applications that cannot be handled by the common "2-wire dedicatedCoriolis flowmeter".
◉Despite the 2-wire transmission, not only analog signals but also flow pulses and flow alarms can be acquired.
◉As a pulse output can be obtained, mechanical totalizing flowmeter of the type with pulse output without an external
power supply can also be updated to the ALTImass series. (2-wire cable for pulse transmission can be diverted.)◉Instead of "2-wire dedicated Coriolis", the proven, high-performance, and reliable "ALTImass series" can be used.

ALTImass series dedicated distributor■ Features
1. It can configure a 2-wire system, by using it in combination with the ALTImass series
Coriolis flowmeter, which is renowned for its high performance, reliability, and abundant
supply reference.
2. It can provide pulse output, analog output (source or sink), and upper/lower limit alarms.
3. Distributors can be applied to replace existing 2-wire flow meters such as differential
pressure and area flow meters with precision Coriolis flow meters.
4. A mechanical totalizing flowmeter that outputs pulses without an external power supply
can also be upgraded to a high-precision Coriolis flowmeter by applying a 2-wire cablefor pulse transmission.
5. The 2-wire system configuration reduces cabling costs, even for new installations of theALTImass series.
