MOUNTING LOCATION of TF1100-EP portable clamp on flow meter
The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing is required. An optimum location is defined as: A piping system that is completely full ...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 -
How to resolve the low or no value of S or Q for transit-time insertion & clamp-on flow meter ? What reasons caused it ?
1. Check if the on-site environment meet some special requests as below. 1). Long enough straight pipe length ; 2) The medium can be measured by our meters and must be full water pipe ; 3) Less air bubbles and solids in measured fluids of pipe . 2. Check the pipeline parameter is right, whether t...Read more -
What are the four parameters of industry ? How do you measure it ?
The four industrial parameters are temperature, pressure, flow rate and liquid level. 1. Temperature Temperature is a physical value that represents the degree of cold and heat of the measured object. According to the measurement method of temperature instrument, it can be divided into contact...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 -
The advantages and disadvantages of transit time ultrasonic flow meter among portable, hand-held and wall mounted ones?
1) Measurement characteristics The measurement performance is better for portable and handheld flow meter. This is because their power are battery operated,and fixed meter is adopted by AC or DC power supply, even if the DC power supply, generally from AC conversion. AC power supply has a certain...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 -
How does the transit-time ultrasonic flowmeter measure certain chemical medium ?
When our flow meter measure this chemical liquid,it is necessary to input the sound velocity of this liquid by manual,due to the transmitter of our meter is no option of certain chemical fluids. In general, it is difficult to obtain the sound velocity of special chemical media. In this case,it ne...Read more -
What is the difference between two-wire and three-wire ultrasonic level meter ?
For Two-wire ultrasonic level meter, its power supply (24VDC) and signal output ( 4-20mA ) share a loop, only two lines can be used, this is the standard transmitter form, the deficiency is that the transmission power is relatively slightly weak. Three-wire ultrasonic level meter is actually fo...Read more
