Dongguan Erlang Technology Co., Ltd

Liquid level sensors and flow switches are key components in industrial automation and process control systems, used widely in manufacturing, water treatment, and oil & gas. Dongguan Erlang Technology Co., Ltd. has been operating since 1998, which shows long-term experience in the field and a track record of stability. Being based in China gives them access to a large supply chain and cost-effective manufacturing. However, no work email, phone number, business documents, or account email have been verified — this raises concerns about the company's legitimacy and ability to respond to buyer inquiries. Buyers should request additional verification before placing large orders or sharing technical specifications. Without verified contact details, it's hard to confirm real-time communication or support during order fulfillment.
