How to assemble and disassemble union nuts?

Most commonly, union fittings are to be used on small size flowmeters for convenient installation. For larger size flow meters, the union fitting is relatively difficult to assemble or disassemble by hand. Therefore, wrenches or pliers are recommended to tighten and loosen large size unions.

Relationship between flowmeter, measuring range, and linearity

Turndown Ratio:The ratio of maximum measure capacity to minimum measure capacity. Each flow measuring principle has its own physical limitation, which leads to different measurement ranges. Thus, users are recommended to select a suitable flowmeter based on their required measuring range and environment. Under a wider measuring range 0.3 ~ 10 m/s, the best linearity of all paddle wheel flow meters in the market is 0.5% FS (Full-scale error). If narrower measuring range is acceptable, the user can have better linearity in a smaller measuring range.

The difference between ultrasonic and paddle wheel flowmeters

The difference between ultrasonic and paddle wheel flow meters 1. Necessity of pipe cutting. 2. Effects to measuring accuracy and attrition by the variety of fluid’s physical properties.

Common on-site monitoring issues with the transit-time ultrasonic flowmeter

Ultrasonic flow meters mainly rely on the sound velocity of the liquid to be measured to calculate the flow rate. However, sound velocity of the liquid will be affected by two common factors, liquid temperature and chemical concentration.

Hysteresis function for alarm output of paddle wheel flowmeters

Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. (Citing source: Wikipedia)

How to choose an installation location of the paddle wheel flowmeter?

Impurities, pressure, water volume, bubbles, etc. are factors to affect flow meter measurement. For avoiding these factors to make sure on-site operation works well, LORRIC recommends that carefully choosing suitable installation location before installing flowmeter will efficiently get rid of these mentioned factors. Through below simple guideline for correct flowmeter installation location on vertical and horizontal pipe LORRIC builds up from decades of client service and on-site experience, it is easy for users to increase the accuracy of flow measurement for successful on-site management.

What is water hammer?

Water Hammer is a pressure surge or wave caused when a fluid, usually a liquid but sometimes also a gas, in motion is forced to stop or change direction suddenly; a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. This pressure wave can cause major problems, from noise and vibration to pipe collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks, surge tanks, blowoff valves, and other features.

How to choose the appropriate flow meter for your application?

As we have all seen, there are various kinds of flow meters deriving from 10+ theories of flow measurement that leaves clients in a limbo as to what product can meet their requirements. LORRIC, as a professional developer and manufacturer works closely with end users to closely understand what their needs and problems are. Therefore, we are deeply aware of what issues and questions clients might have and we’re able to provide consulting and professional suggestions to prospective users.

The two new forms of innovation users get to experience through LORRIC’s sensors

After interviewing and associating with over a thousand flowmeter users, getting a deep insight into their on-site work environment, we discovered that on-site factory management, as a consequence of automation, requires on-site personnel to have a larger inspection range than before. That combined with a less than ideal line of sight inside the factory environment, all contribute to make on-site management difficult. In order to increase on-site management efficiency, we believe that apart from the machinery’s sensing capabilities, screen redesign can be the other key to solving user pain points.
