Our prepaid water meters represent a significant advancement over traditional mechanical water meters by integrating electronic modules. This integration facilitates a user-friendly prepayment system, where customers pay for their water usage in advance. This approach simplifies the process for both water utility providers and their customers. We offer these prepaid water meters in two size ranges: small diameter (DN15-DN50) with threaded connections for residential and smaller applications, and large diameter (DN50-DN200) with flange connections for larger, commercial uses.
