Product Description

1. Product overview:
TLU ultrasonic water meters are specially designed for urban water supply pipeline metering and household metering by means of propagation velocity difference, with the characteristics of low start-up flow, zero pressure loss, no movable parts, long-term stable operation and high reliability.

They solve the problems of high start-up flow and non-metering of small flow of traditional water meters, and meet the needs of industrial use and have functions of calibrated pulse output, 4~20mA current output and RS-485 communication, applicable to various industrial sites. This product conforms to GB/T 778-2018 Drinking Cold Water Meter and Hot Water Meter. The delivery inspection is in accordance with JJG162-2009 cold Water Meter.
2. Main Aavantages:

• No mechanical movable parts,no maintenance, stable and reliable.
• With built. in single lithium battery, it can work continuously for more than 8 years. Ultra -low start-up flow solves the problem of high start-up flow and non metering of small flow of traditional water meter.
• Range ratio is up to R400.
• Protection grade lP68, for long-term underwater operation.
• Dual direction metering function.
• lt is impossible to modify important parameters and data after they are exworks for data safety.
• Monthly cumulative flow, daily cumulative flow and hourly cumulative flow in the last 72 months can be recorded and queried.
• It has the functions of pulse outout.4-20mA curent outout, Rs-485 /M-BUs communication, wireless hand-held meter reading and GPRS wireless communication.
