What problems should be paid attention to during the installation of high temperature medium?
As for as our ultrasonic flow meters are concerned, Clamp-on / external clamp transducers can measure the upper limit of liquid temperature that is 250℃ Insertion transducers can measure the upper limit of liquid temperature that is 160℃ In the process of installing the clamp on sensors, pls not...Read more -
What is the request of upstream and downstream flow for measured pipe ?
When the flow meter is installed, the liquid flows, the direction of liquid entry is upstream and the direction of liquid discharge is downstream . For measuring liquid flow by ultrasonic flowmeter, the straight pipe section is required as a certain length of the water inlet and outlet of flow me...Read more -
Working principle and application field of ultrasonic level gauge and ultrasonic thickness gauge
The working principle of the ultrasonic level meter is that the ultrasonic transducer (probe) emits high-frequency pulse sound wave, which is reflected when it meets the surface of the measured object level (or liquid level), and the reflected echo is received by the transducer and converted into...Read more -
What is the blind area ( dead zone) of ultrasonic level meter/ level sensor/level transmitter ?
When ultrasonic level meter is transmitting ultrasonic pulse, liquid level meter can not detect the reflection echo at the same time. Because the transmitted ultrasonic pulse has a certain time distance, and the probe has residual vibration after transmitting the ultrasonic wave, the reflected e...Read more -
TF1100 non contact ultrasonic flow meter water liquid measurement— Window Descriptions
The TF1100 has a unique feature of windows processing for all operations. These windows are assigned as follows: 00～08 windows for the display of flow rate, velocity, positive total, negative total, net total, heat flow, date & time, meter run status etc. 11～29 windows for initial Parameter...Read more -
What is the main applications of TF1100 serial clamp-on ultrasonic flow meter ?
General : The non invasive flow transducers that are utilized by the Series TF1100 contain piezoelectric crystals for transmitting and receiving ultrasound signals through walls of liquid piping systems. The clamp-on flow sensors / transducers are relatively simple and straight-forward to instal...Read more -
What is Modbus-RTU communication protocol of Lanry flow meter ?
Modbus protocol is a universal language used in electronic controllers. Through this protocol, controllers can communicate with each other and with other devices over a network (such as Ethernet). It has become a universal industry standard. This protocol defines a controller that is aware of ...Read more -
What is RS485 communication ports of Lanry brand meter ?
The RS485 communication port is a hardware description of communication ports. The wiring mode of the RS485 port is in the bus topology, and a maximum of 32 nodes can be connected to the same bus. In RS485 communication network generally adopts the master-slave communication mode, that is, a hos...Read more -
What points should be paid attention to during the installation of high temperature medium ?
The upper limit of high temperature is 250℃ measured by the clamp sensor and 160℃ measured by the insertion sensor. During sensor installation, note the following: 1) Wear high temperature protective gloves and do not touch the pipe; 2) Use high temperature couplant ; 3) The sensor cable ...Read more -
What points should be paid attention to when comparing transit-time ultrasonic flowmeter with electromagnetic flowmeter on-site ?
1) Electromagnetic flowmeter need straight pipe that is shorter than ultrasonic flowmeter’s. Electromagnetic flowmeter installation site may no longer straight pipe, so compare at the scene, pay attention to the position of measuring whether can meet the requirements of straight pipe ultrasonic f...Read more -
What historical data is stored in ultrasonic water meter ? How to check ?
The historical data stored in ultrasonic water meter includes the hourly positive and negative accumulations for the last 7 days, the daily positive and negative accumulations for the last 2 months, and the monthly positive and negative accumulations for the last 32 months. These data are stored...Read more -
Why are temperature and flow transducers installed in pairs, and what is the impact?
When you use temperature and flow transducers,it is usually used in pairs. The reasons as below. For flow transducers,it can decrease the deviation of static zero; For temperature transducers,it can reduce the deviation of temperature measurement. (by using two sensors with the same error value )...Read more
