Supplier of H2S sensing devices for wastewater network
As part of continuous H2S monitoring in a wastewater system, where the measuring point is difficult to access, we decided to centralize the material to be analyzed and to physically go to the desired point and take a sample via gas suction. (And not by placing the sensor in the area to be analyzed))
So we had ASCO make us some sampling cabinets (78) of 1.2 and 4 channels. Each channel consists of: a pump (6 liters/minute), a BW sensor ref: XNXSIL 2 with 4-20mA output, fixed line (0-500ppm), a flow rate ”divider" (to limit flow to the sensor to 1 liter/min flow), a ball-flow meter, a control switch and a settling tank. A device for the data transmission..
The benefit/main point of this concept is to ensure the material to be analyzed remains outside the confined area, especially when the measuring point it is at a great depth or under a heavily trafficked road.
