Aneroid bellows

• AB-815
• This bellows is connected directly to the atmospheric relief pipe of an immersion-type water level meter. It blocks outside air to prevent dew condensation inside the water level meter due to humidity. If the periodical maintenance of the meter is impractical, install this aneroid bellows. While the atmospheric pressure can be corrected when measuring the water level, the bellows is not suitable if precision of ± 0.25% F.S. or higher is required.
