Structure Principle - HollySys HT5 Series Instructions For Use Manual

HT5 series metal tube flowmeter
user requirements, vertical mount (HT50), progress under-mount (HT51), side into the side
mount (HT52), end into the side-mounted (HT53), threaded connection type (HT54),
horizontal-mounted installation (HT56R / L) and other options.

Structure principle

2.2
HT5 series metal tube composed of two parts:
Measuring tube - magnetic couplings, sensors;
Indicators - signal conversion, conditioning, or a
digital display indicating the scale;
Wetted material of the measuring tube there are four:
stainless steel, Hastelloy, titanium, stainless steel
lining PTFE; the user may require different process
pressure corrosive media and select different wetted material to meet process pressure
corrosion and media needs. Depending on the measurement requirements, users in the selection,
you can select a different combination of indicators, to achieve different measurement
requirements. Specific type indicator corresponding function indicator see chapter.
the float rises to a position of the cone relative to a stationary, then flow area changes,
the float suffered three a force equilibrium (gravity + = thrust buoyancy), this position
by the close magnetic coupling transmission shaft driven pointer and components, completion
pointer flow indication, through the modular design of the converter is converted to the
flow rate corresponding to 4 ~ 20mA / Hart output. Change the position of the float, that
reflects the changing media traffic.
Measuring principle
Relative to a medium flows
through the sensor fixing
condition, when the flow
rate reaches a certain
flow design flow range,
