4-20mA output introduction
Many industrial meters choose to use current to transmit signals, because current is not sensitive to noise. The current loop of 4 ~ 20mA is 4mA to represent the zero signal, 20mA to represent the full scale of the signal, and the signal below 4mA and above 20mA is used for the alarm of various ...Read more -
Why is the 4-20MA signal used in industry and not the 0-20MA signal?
The most widely used standard analog quantity electrical signal in industry is to transmit analog quantity with 4~20mA DC current. The reason for using the current signal is that it is not easy to be interfered with, and the internal resistance of the current source is infinite. The wire resista...Read more -
Magnetic flowmeter introduction
Electromagnetic flowmeter Electromagnetic flowmeter is a kind of induction meter which is made according to Faraday’s law of electromagnetic induction to measure the volume flow of conductive medium in the tube. In the 1970s and 1980s, the electromagnetic flow has made a great breakthr...Read more -
vortex flow meter introduction
Vortex flowmeter Vortex flowmeter is an instrument in which a non-streamlined vortex generator is placed in the fluid, and the fluid alternately separates and releases two series of regular staggered vortices on both sides of the generator. Vortex flowmeter is one of the youngest flowmeters, but...Read more -
Coriolis mass flowmeter introduction
Coriolis mass flow meter is a direct mass flow meter made of Coriolis force principle which is proportional to the mass flow rate when the fluid flows in a vibrating tube. Can be used for liquid, slurry, gas or steam mass flow measurement. Overview of Application: Mass flowmeter not only h...Read more -
Ultrasonic flowmeter
As ultrasonic waves travel through a moving fluid, they carry information about the velocity of the fluid. Therefore, the received ultrasonic wave can detect the flow rate of the fluid, which can be converted into flow rate. According to the detection method, it can be divided into different ty...Read more -
The ultrasonic flowmeter can be installed according to the following steps:
The ultrasonic flowmeter can be installed according to the following steps: 1. Observe whether the pipeline at the installation site meets the distance requirement, it asked upstream 10D and downstream 5D, D is pipe size. Even if we can not ensure 10Dand 5D, at least upstream 5D and downstream ...Read more -
What are the reasons for the difference in readings between the ultrasonic/electromagnetic insertion flowmeter or the turbine flow meter?
1) Firstly, For the working principles of the insertion electromagnetic flowmeter or the insertion turbine flowmeter. Both belong to the point velocity measurement principle, while the ultrasonic flowmeter belongs to the linear velocity measurement principle, and after the velocity distribution c...Read more -
What points should pay attention to when installed insertion sensors ?
When installing insertion sensors, the following points need to be pay attention to. 1) Insertion ultrasonic flowmeter requests: Pipeline pressure shall not be greater than 1.6mpa; 2) Use the Lanry proprietary insertion online installation tool for installation; 3) Do seal well and wrap th...Read more -
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 -
SC7 ultrasonic water meter introduction
The low starting flow, minimum flow rate is lower than the 1/3 of the traditional water meter； Bi-directional flow measurement The water temperature detection, temperature alarm; No moving parts, no wear, can be long-term and stable operation; The power supply of water meters is ensured by a 3,...Read more -
The Ultraflow QSD 6537 requires very little maintenance. During routine site visits the following checks can be performed:
Piezo Element Faces Clean the instrument surfaces where the Piezo elements are located by wiping with a cloth. If needed a plastic scraper can be used to remove any bio-fouling. Take care not to scrape the surface of the instrument. Refer to the above diagram for the areas where the ultrasonic ...Read more
