1. Product Information
DCT1158SE is a micropower, low starting flow, battery-powered ultrasonic flowmeter. It uses high-energy long-life battery, with micro-power battery, high efficiency electro-acoustic conversion device, make wild, outdoor and power shortage of pipe flow metering is possible. DCT1158SE is also an industrial ultrasonic flowmeter. It uses metal flameproof enclosure, with a high level of protection and sealing, suitable for all-weather even bad climate, can also be applied to high temperature humidity and dust. It uses ultrasonic flow measurement technology, no mechanical moving parts, high reliability, low maintenance, built-in battery up to 10 years of continuous work,(Both external power supply). It is no pressure loss, low power consumption, low starting flow (0.005m / s), high accuracy, resist the impact of large water flow, can be a long and stable operation at maximum water flow rate, at the same time for fire water metering. It uses a focused acoustic patented, make the products in the continuous measurement of reception quality was significantly enhanced.
DCT1158SE pipe-stage ultrasonic flowmeter uses an advanced design module function, Transmitter protection to IP65, sensors protection to IP65, suitable for use under wet conditions.The product according to your needs, choose the one-piece or two separate transmitter installation, meet your needs of different working conditions.
DCT1158SE collection of the current RS485 / RS232 communication interface used in industrial applications,4-20mA current signal, pulse output ,Modbus protocol, , may constitute a flow measurement network requirements.
2. Features

Site selection principles
1. Should avoid clock 6 or 12 point position, so as to avoid sediment at the bottom of the pipe or pipes upper part of the bubble, air-pocket caused by signal attenuation.
2. Fully considering the tube wall scaling condition, as far as possible choose no scaling section measuring, can fully meet, need to think about scaling for lining in order to get better the measurement accuracy.
