<1>OUTLINE
Smith4011 Branch mass flow meter used to test the quality of flow in the pipeline. And other flow measurement methods, compared: A direct measurement of the fluid pipeline quality, high measurement accuracy, repeatability, and can range in the larger context of the fluid quality to achieve high accuracy direct measurement. Flow meter pipeline with no obstruction and internal moving parts, thus high reliability, long life and maintenance of small convenience and safety. B, Adapt to the fluid medium＇s surface is very wide. Apart from the general uniformity of fluid viscosity, high viscosity can be measured, non-Newtonian fluid; single solution can be measured not only the fluid parameters, but also can be measured more uniform mixing multiphase flow, whether media is filled with laminar flow or, not affect the measurement accuracy.
A wide range of applications: in the petrochemical, pharmaceutical, paper, food, energy and other fields of measurement and monitoring.
Good anti-corrosion properties: Common apply various corrosive fluids.
Real-time monitoring and control a variety of functions: In addition to mass flow, but also the direct measurement of fluid density and temperature. Intelligent flow transmitter can provide a wide range of parameters of display and control functions, is a multi-functional integrated set of flow measurement and control instrumentation.
Scalability of the good: According to user needs, the specialized design and manufacture of special specifications and special features of the Model mass flow meter; operation can be carried out, such as remote monitoring.

<4> Installation environmental requirements
Smith4011 of quality flow meter is a high-accuracy measurement instruments, in order to ensure accuracy of measurement, the need to ensure the installation of environmental requirements: (1) sensors (one table) and the transmitter (second table) may not be installed in a strongly magnetic interference Regional Otherwise, it will affect circuit signal, thus affecting the measurement accuracy;
(2) The pipeline of sensor (a table) installation can not have other vibration interference;
(3) The need to install outdoor circumstances, we should pay attention to the highest environmental temperature, should consider measures to prevent the wind and rain to enhance flow meter working life;
(4) The type of second flow meter placed in the control room instruments or the appropriate security zone;
<5>Flow meter basic specifications and flow
 Products are divided into intrinsically safe and explosion-proof two types, each type of instrument by the sensor (one meter) and the transmitter (second instrument) consists of two parts.
Sensor (second instrument) instrument is part of the show, loaded with vibration, displacement and Sensors. Transmitter (second instrument) instrument is part of the show, is also part of the electrical instrumentation. With its internal power supply, analog circuits, digital circuits, display and output, and its basic functions are: to accept and deal with the sensor signal, processed by direct mass flow, temperature and density, and in accordance with the above parameters, such as flow export volume for the measurement parameters can be displayed, export, storage and remote transmission, modify flow meter parameters. Transmitters are equipped with internal Security Gate, isolation from the explosion-proof protection.
<6>Product Selection
This product is intrinsically safe type flow meter, the sensor (a table) can be explosive gases in the environment under the use condition, the transmitter can only be provided in an urban environment, not on the danger area; Flameproof flow meter, its sensor (a table) is intrinsically safe transmitter (second table) is flameproof, sensor and the transmitter can be explosive gases in the working environment can be on the danger area.
