1. Pay attention to fabrics and colors
The sofa in the living room, the fabric is better with a thicker velvet or cloth sofa, and the color should be in harmony with the interior decoration style. The sofa in the bedroom, in addition to the overall coordination with the interior decoration style, should choose warm, romantic and quiet colors; the choice of fabrics is comfortable with knitted nylon and long-wool fabrics, which makes them feel warm. Elegant, giving a comfortable feeling.
2. Scrutinize the structure of the sofa
Before choosing a sofa, the consumer can push the sofa to the left and right by hand to see if the overall structure of the sofa is firm. If the hand feels shaking or making a sound, the structure is not firm. When pushing the sofa, is it free to slide and the screws are full. If the sofa is made up of decorative panels or plywood, it is necessary to look closely at the adhesion between the two materials and whether there is any damage. Especially for the steel-structured sofa, the weld is a key. Open the part that can be opened as much as possible. Look carefully and carefully to avoid loosening and collapsing after sedentary. If it is a wood-structured fabric sofa, the main frame part is generally made of a shackle structure. If it is found that the inner frame is all assembled by nails, it must not be purchased.
3. Pay attention to the hidden parts of the sofa
Consumers should be aware that general furniture merchants introduce their strengths when introducing their products. For those things that are avoided, such as the sponge of the sofa, if the feel is uneven, or if there is no elasticity when sitting down, such a sofa should be bought with caution. Secondly, pay attention to some details, such as whether the exposed metal attachment has metal burrs and sharp angles; whether the armrests of the sofa are uneven or not.
Sealand is a trustworthy supplier of Mass Flow Transmitter, Mass Flow Sensor, Mass Flow Metre, Coriolis Metre, ATEX, IECEx & CE approved.
Sealand Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
Features
â— Measurement is not influenced by flow density, viscosity, temperature & pressure;
â— Low requirement of straight pipe, because nothing inside holds back the flow;
â— Low power dissipation; stable zero point; better accuracy;
â— Meter is ARM system with 3 calculators to count density, temperature & mass flow rate;
â— Transmitter is assembled by surface mounting technology with self-inspection function;
â— ATEX approved(excluding Transmitter F210). Cert. No. TPS 18 ATEX 04516 001 X
