美国采购需求：水流量计供应商、工业流量测量、水系统流量计、购买水流量计、流量计制造商、数字水流量计

I'm looking to get some detailed info on your wholesale pricing for water products. Specifically, I would like to know about the various pricing tiers you offer, as I'm interested in understanding how quantity affects pricing. If you have different products or sizes within your water category, please include that info too. Additionally, if there are any promotional discounts available for bulk orders or contract purchases, I'd love to hear about those options. Having a clear breakdown of the pricing structure would be super helpful for my procurement plans. Let me know if you need any more details on the quantities I'm considering. Thanks!
