Barton 351 Liquid Level Systems
As stress on the bellows differs owing to fluid type and/or process device stress differences, these stress differences are transferred to the reader through the liquid packed sensor and capillary tubing. The S048 sensor is designed for mounting purposes with the same housing as the 500-psi SWP sensor, but has no pressure rating and is designed for mounting inside open vessels or sumps. The sensor’s large bottom opening prevents the sensor ports from fouling due to dirt, loose debris, or other contamination.
All sensors have housings in stainless steel. The capillary tube connecting the sensor to the DPU is either 1/4-in. Or in 3/16-in. OD. The setup determines the tubing duration. As required, capillary tubing may be bent or looped. A 1/4-in. NPT connector or high-pressure insert (3/8-in. OD tube) in the building promotes venting. A fluid stack exerts a stress equal to its height and density, regardless of the form or quantity of the carrying unit. A differential strain device (DPU) can be calibrated to show a fluid’s height when the fluid density is recognised. The weight and quantity of goods can be evaluated by a DPU in bottles of specified sizes.
