Focus Level Measurement and Control Yokogawa Levelese Ambient temperature swings handled by this DP transmitter For tanks located outdoors, ambient temperature conditions can interfere with level measurement due to the expansion and contraction of oil inside capillary tubes that are connected to diaphragm seals. The EJXC80A Diaphragm Seal System (photo) was designed with a unique compensating capillary specifically to address this issue. The compensating capillary is an additional capillary tube on the high-pressure side of the transmitter that balances the volume of fill fluid with the capillary on the low-pressure side. This allows both the high- and low-side fill fluids to be exposed to the same conditions and effectively eliminates errors caused by changes inhttp://www.levelese.com http://www.yokogawa.com/us http://www.emerson.com http://www.Chemengonline.Com
