Meriam 1126P-2 Portable Indicator, 1120 Series Differential Pressure Units Product User Manual

Hello! I've reviewed the user manual for the Meriam Instrument Bellows D/P Indicators and Switches, including the 1120, 1220, and 1020 series. I understand these devices are designed for differential pressure measurement using bellows, offering features such as field-adjustable pulsation dampening, temperature compensated linkage and various mounting configurations. The manual also covers how to install, operate and maintain these devices. I am here to help you with any specific questions you may have.
What is the operating temperature range?

What is the maximum differential pressure range?

What is the pulsation dampener adjusted?

What kind of switch is used in the indicating switches?

What is the accuracy of the indicators?
