1. Product Information

　　DCT1158W is a widely used, versatile, clamp-on, transit-time ultrasonic flowmeter, It has a very simple installation, without breaking the tube, no disruption of water supply, enables customers to easily implement flexible pipe flow measurement, products can also be equipped with a permanent clamp-on installation, without daily maintenance，long-term to provide credible, no deviation measurement. It uses the most advanced digital technologies and intelligent adaptive acoustic technology, measurement stability make it more prominent, At the same time, it uses a focused acoustic patented, make the products in the continuous measurement of reception quality was significantly enhanced.

　　DCT1188W Standard configuration as shown: ① Transmitter ② Sensors

　　③Brass ball valve④ Carbon steel base

　　DCT1158W series products are made up of transmitter and sensor. Insertion sensors can be Online installation with pressure, it has the advantage of firm installation and the scene without shutdown ,etc. Are particularly well suited for measuring small amounts of single liquid medium containing the particles and air bubbles.

　　DCT1158W uses an advanced modular design, independent menu operation, LCD backlit display, product transmitter protection grade reaches IP65, Suitable for harsh environments such as moisture and soaking.

　　DCT1158W collection of the current RS485 / RS232 communication interface used in industrial applications,4-20mA current signal, pulse output ,Modbus protocol, DC/ AC power, support product all-weather work, may constitute a flow measurement network requirements. In addition, the product can be extended to use solar energy, mine supply (Rem power) explosion and other functional modules, so that products can meet a variety of application environments.

　　The 2014 version DCT1158W series ultrasonic flowmeter, use of the currently most popular golden material, good sense and high pressure plastic fuselage, strong and lightweight, dual-function keys, Operation more efficient, simple, convenient, also uses a new FPGA delay line measurement techniques, with high dynamic advantages, sampling rate of 200 times / sec.

　　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.
