Introduction
Modular type ultrasonic flow meter is one type ultrasonic flow meter with small size and competitive price. It's working based on transmit-time working theory. One ultrasonic sensor send ultra-sound wave and another one sensor could receive this wave. The transmit time from send to receive have relationship with the velocity of flow speed. Then, converter could calculate the flow speed based the transmit time. 
Advantages
Modular Type Ultrasonic Flow Meter Advantages and Disadvantages
1. Modular type ultrasonic flow meter is different with other type ultrasonic flow meters. It have much smaller size and could be installed into instrument box easily via DIN rail. It will save installation space.
2. It have multiple functions, such as LCD display, 4-20mA, pulse and RS485 output. No pressure loss, measurement is not affected by temperature and pressure changes. And the accuracy for it could reach ±1%.
3. Reliable empty full tube detection technology, Excellent low flow rate measurement performance, turndown ratio 100:1.
4. As a professional manufacturer, we could produce it with solar panel power system also. It's very convenient for working site where don' t have external power supply. 
Application
Modular type ultrasonic flow meter used in tap water, heating, water conservancy, metallurgy, chemical, machinery, energy and other industries.
It can be used for production inspection, flow verification, temporary inspection, flow inspection, water meter horizontal debugging and energy saving monitoring.
It is a tool and meter for timely detection of flow.

Installation
Modular Type Ultrasonic Flow Meter Installation  
"V" method installation:
The "V" method installation is a relatively standard installation method, which is easy to use and accurate in measurement. When installing the two sensors, the center line of the two sensors can be aligned horizontally with the axis of the pipeline. It’s used on DN15mm and DN400mm.
"Z" method installation:
"Z" method of installation is the most commonly used method also. It is characterized by direct transmission of ultrasonic waves in the pipeline, no reflection (called single sound path), low signal attenuation loss. It’s used on DN100mm to DN6000mm.

Modular Type Ultrasonic Flow Meter Maintenance
1. Always observe whether the sensor power cable and transmission cable (or wire) of the instrument are damaged or aging. You need to protect the rubber sheath outside the cable.
2. For the clamp on type transducer ultrasonic flow meter, it is necessary to check whether the transducer is loose or not; whether the adhesive between it and the pipe is normal.
