About Haina Meter
Haina Meter Instrument Co., Ltd. manufactures industrial flow meters and level transmitters in Liaocheng, Shandong, China. Our product lines cover electromagnetic, vortex, metal tube rotameter and target flow meters, radar and magnetostrictive level transmitters, magnetic level indicators, purge systems and loop displays.
From our plant in Liaocheng, Shandong, we supply flow meters, level transmitters, level gauges and switches to project contractors, OEMs and distributors. Every model in the online catalog lists its full parameter table, so engineers can verify sizing before they enquire.
Models are supplied directly from our Liaocheng plant — no trading-company markup, and OEM labeling is available on request.
Send us medium, pipe size, flow range, temperature and pressure — engineers reply with a model recommendation and the full datasheet.
Export-grade packing with the documents your customs broker needs: invoice, packing list and product manuals in the box.
Wiring diagrams, parameter help and troubleshooting by email or WhatsApp after delivery — from the same team that built your meter.
Tell us your medium, pipe size, flow range, temperature and pressure — our engineers will recommend the right model.
