Recent rumors about Apple's new iMac continue, and now users have released a new iMac configuration keyboard picture, it is really difficult to distinguish. It is said that the new iMac keyboard will use metal aluminum keyboard frame, the surface is brushed, is an ultra-thin keyboard. There are also some new iMac keyboard details compared to the new and old versions of the keyboard. Let's take a look. Previously there was rumors that the new iMac will be available on August 7 and will use a surface-drawn aluminum housing. Apple's products have always been of great concern. How about the new iMac, let us wait and see.
Zhejiang Sealand Technology Co., Ltd.is a trustworthy supplier of Oil Mass Flow Meter, Oil Mass Flowmeter, Oil Coriolis Flow Meter, Oil Coriolis Flowmeter, Oil Coriolis Flow Meter, ATEX, IECEx & CE approved.
Operating Environment
Atmospheric pressure: 85kPa~106kPa
Ambient temp.: Refer to Chapter 1.6
Relative humidity: 5%~95%, non condensing
Operating conditions
Fluid: Liquid/Gas
Nominal pressure: 4MPa or 25MPa (Customizable)
Supply voltage: AC 85~265VAC, 50/60Hz or DC 12~24VDC(±5%), 5W

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed
of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
