STW36-M Woltman Prepaid Bulk Water Meter Irrigation Water Saving
Remote Control
STW36-M is developed on basis of dry type Waltman Bulk water meter,
electronic board with STS (Standard Transfer Specification)
compliant prepayment, diaphragm pilot-actuated valve controller. It
is composed of a prepaid water bulk meter and a separate customer
interface unit (CIU) with LORA-RF wireless communication module.
They are available to communicate with AMI system for data
transmission.
Basic Functions
✽ Muti-jet Dry dial register construction
✽ Low Power Consumption
✽ Programmable low credit warning
✽ Recharge by customer interface unit(CIU)
✽ Brass / plastic meter body on request
✽ Non- return valve preventing back-flow
LORA-RF wireless communication optional can be read or controlled
by our AMI server, customer can check data and parameters they
need, like monthly consumption, daily consumption, meter status.
Service provider can close the valve remotely, Effectively prevent
