has to be provided with a sufficient sample water stream. It measures the oil
content, and transmits the measured data to the computer unit.
The Measuring Cell has all parameters and calibration data permanently stored,
and the calibration certificate is tied to the Measuring Cell. The recommended
way to renew a calibration is to exchange the Measuring Cell. Under no
conditions should the Measuring Cell be opened or dismantled, doing so would
void both warranty and calibration.
5.4 FW valve
The OMD-2008 uses a switchover valve to control the usage of clean water for
cleaning, or zeroing purposes. Whenever the FW valve is switched to Clean
water position, and not to sample stream position (normal operating position), the
instrument will be in alarm condition.
The valve can be manually operated (OMD-2008), or electrically operated (OMD-
2008 EV). The electric valve can be switched using the programming mode.

5.5 Other devices

Measuring Cell and the valve to switch over from sample water stream to clean
water usage (FW valve) are mounted onto a stainless steel support. The clean
water valve may be a manual switchover valve, or an electric valve, and controls
sample water and clean water usage. A Flow Sensor, or a Manual Cleaning Unit
(MCU) may also be installed.
The OMD-2008 EV-FC can easily be mounted in wall or bulkhead installation.
