The WATC is designed to be used with detector tubes available in the industry. Through the controlled extraction of the gas or liquid from the process into the cylinder, the product is sampled without escaping or venting into the environment. Once drawn into the cylinder, the pressure is reduced to atmospheric, and the detector tube is installed. The product is then pushed through the tube, and into the back side of the cylinder for safe disposal. The operator is not exposed to the product, and the process is simplified.

Welker offers a wide variety of cylinder sizes, materials of construction, pressure ranges, and specialty coatings for the WATC.

The EnPro HSS Series Hand Operated Spot Samplers are designed and constructed to provide industry with a spot sampler or product transfer device that can collect low pressure gas or liquid samples from pipes and vessels.

The product can then be pressurized by hand or by introducing a pressure gas source to the underside of the piston. This will enable the introduction of the sample or product to an analyser or presurised pipeline. The sampler has an abundance of available features to suit individual operational requirements. It can be easily carried and operated and can also double asa constant pressure sample cylinder.

The SCA series of sample cylinders provides a range of small cylinders with a choice of materials, configurations and sizes. The options offered by this unique design have previously not been available in alloy metals. The two piece construction allows the inside surfaces to be smooth machined, thereby flush cleaning is aided and residual samples will not be trapped in crevices or rough machined surfaces.

It is also available in a one piece welded construction.

The EnPro LPG Residue Test Cylinder is designed to provide LPG samples that will not leave residues.

Internal electopolishing ensures that cleaning is effective, as a result of that there is no contamination of subsequent samples.

The cylinder has a cylinder valve with fixed level gauge and ullage tube to limit filling to 80%.
