The single flange is used to measure the liquid level of the open tank.
Differential pressure range calculation method: need to measure the liquid level height (unit: m) × gravity acceleration (9.8) × measured medium density (unit: g / cm3, when the density of water is calculated as 1, the unit is g / cm3) Range (unit: KPa).
The type selection must know the measuring medium, measuring range, medium temperature, process connection flange size and pressure rating and flange standard.
Double flange is used to measure the liquid level of the closed tank.
Differential pressure range calculation method: need to measure liquid level height (unit: meter) × gravity acceleration (9.8) × (measured medium density-capillary filling liquid density) (unit: g / cm3) = differential pressure range (unit: KPa ).
The type selection must know the measurement medium, measuring range, medium temperature, pressure, capillary length, process connection flange size and pressure rating, and flange standard.
