WIKA All-Welded System (AWS) Prevents Gauge Failure in Growing Ethanol/BioDiesel
Industry
The United States has seen an explosion of new Ethanol plants and many more are
in development. WIKA manufactures many product configurations engineered with specific
design features and gauge options for utilization in the Ethanol production. Pressure
instruments used in this industry must be rigorous and sturdy enough to withstand
the harsh conditions that occur in the production processes. Mishandling, severe
pulsation, vibration and harsh environmental conditions can compromise system integrity.
These conditions may break the traditional diaphragm seal system, resulting in inaccurate
readings or total failure.
The WIKA All-Welded System (AWS) model M93X.D1 is an integrated process gauge –
diaphragm seal system. All connections and access ports are welded to ensure complete
leak free design. Because the AWS is engineered as tamper proof and leak proof with
the system fill fluid leak path eliminated, the gauge/seal connection cannot be
compromised. With its rugged design, this seal and gauge assembly can increase its
time of service (= cost of ownership) significantly. The premier assembly for the
bio-renewable fuels is the AWS with 1.0 NPT-male process connection and Flushing
Port. The AWS with a liquid-filled case protects the instrument from mechanical
vibration and pressure pulsation. A flushing port added to the lower housing of
the diaphragm seal allows cleaning fluid to flush residue out of the pipe in order
to prevent damage or clogging to the instrument.

Decontaminating Fluid Syststemsn
Unwanted water, particulate and gaseous contamination in fluid systems can severely
impact process efficiency and product quality. Utilizing the principles of mass
transfer and vacuum dehydration, the Pall HVP series portable oil purifiers effectively
and efficiently remove 100% of the free water and 80% to 90% (or more) of the dissolved
water from the fluid system. They will also remove 100% of the free and entrained
gases and up to 75% of the dissolved gases.
Highly efficient particulate removal can be achieved by using a single, Pall Ultipor
III style element rated at Beta X(c) = 1,000, in accordance with ISO 16889. Cleanliness
levels of ISO 16/14/12 (per ISO 4406:1999) or better are typical. The HVP employs
a programmable logic controller (PLC), which monitors and sequences its operation.
The PLC will automatically shut down the purifier in the event certain operating
limits are exceeded and initiate the purifier diagnostic alarm and help screen.
This will display all alarm conditions, probable cause of the alarm(s) and help
screens that delineate corrective measures to rectify them. An in-line temperature/water
sensor is mounted at the inlet of the purifier, which continuously monitors fluid
temperature and water content. It provides both local and remote monitoring capabilities
and can be programmed with various alarm points for temperature and water content.
These units are very portable and easy to install. They only require an inlet and
outlet connection to the fluid system and the appropriate power source – 480v/3Ph/60Hz.
There are no water or compressed-air line connections required. They will reduce
system wear; improve on-line and system performance; extend fluid life; and reduce
fluid disposal costs and environmental risks.
