英国采购需求：超声波距离传感器、超声波液位传感器、避障传感器、气泡检测器

I'm looking to place a bulk order for a specific type of LPG level measuring sensor that you manufacture. Can you provide me with details regarding pricing, minimum order quantities, and any available discounts for large purchases? Additionally, it would be helpful to know about lead times for delivery and any certifications or standards that your product meets. I'm eager to explore potential business collaboration, so your prompt response will be greatly appreciated!
