The Varec Biogas 217 Series Well-Type Manometer is a direct reading, singletube type pressure gauge, which provides both long-term reliability and high precision for accurate pressure measurement. This is extremely important in a low-pressure waste gas system because it is an indication of digester efficiency. If a U-Tube type Manometer is required, refer to Varec Biogas 219 Series.
The 217 Series Manometer should be installed in waste gas piping wherever local pressure, vacuum, or differential pressure measurement is required. Recommended locations are:
• gas lines leading from digesters and
low pressure gas holders.
• gas lines leading to boilers, engines,
and other plant utilities.
• upstream of the pressure regulator
installed immediately upstream of the
waste gas burner.
These manometers are standard in ranges up to 30” Water Column (WC) (using Indicating fluid).
