Core Strengths

Entire stainless steel build paired with PTFE media-contacting components delivers good anti-corrosion performance. It can handle harsh dosing agents including biocide and corrosion inhibitor without material deterioration.

Flameproof construction together with IP65 ingress protection and ATEX EEx d IIA T3 approval allows safe mounting in hazardous classified zones, for indoor and outdoor deployment.
Broad temperature working range from -40℃ to 150℃ supports stable operation in cold surroundings and heated process piping.

Two available power supply selections of 24VDC and 230VAC simplify integration into varied site electrical infrastructures.

Optimized for low flow measurement with a 100 L/h maximum flow setting. It fits chemical injection pipelines and offers reliable flow confirmation to secure dosing system operation.

Application Scenarios

This unit is made to verify flow status on chemical dosing assemblies. It mainly serves biocide and corrosion inhibitor injection pipelines in oil and gas, water treatment, and petrochemical plants. It monitors continuous dosing flow and triggers alarms for no-flow or low-flow conditions, preventing downstream hardware damage caused by insufficient chemical supply or pump dry running.
