Made in China Hs-2000 intelligent external ultrasonic level meter
Overview
Hs-2000 intelligent external type ultrasonic level meter (referred
to as "external measurement level meter") can be in the tank
outside the continuous measurement of liquid level, but also
especially suitable for closed container in a variety of toxic
substances, strong acid, strong alkali and all kinds of pure liquid
level measurement, the instrument adopts flameproof design, can be
used in the need of explosion-proof occasions.

Working principle
Hs-2000 external ultrasonic level meter using sonar echo ranging
principle, to overcome the impact of the tank wall on the
ultrasonic signal, using digital signal processing technology, can
truly achieve non-contact, measuring tank level. The level meter can output 4~20mA standard signal or output the
measurement results to the upper computer (or secondary table)
through the RS-485 interface to meet the automatic control of the
system.
Product Advantage
NO.1 Non-contact measuring function
ultrasonic sensor (probe) is external, no need to open the measured
container
NO.2 automatic calibration
level gauge with self-calibration function, to overcome the
traditional level gauge after a long time of use, the accuracy of
the problem
NO.3 infrared online debugging function
convenient infrared debugging function, especially suitable for
dangerous occasions should not open the cover debugging occasions; At the same time, the difficulty of debugging is reduced
NO.4 self-diagnosis
level gauge has the diagnostic function of its own working state,
but also has the hardware diagnostic function; This increases the reliability and stability of the level gauge
NO.5 One-click Recovery
When the level meter is abnormal, you can use the debugger to
restore the level meter to the normal state with one click
NO.6 local display and remote transmission function
level meter can be convenient to display the liquid level value in
the field, and can be transmitted to the control room through the
signal line
Application condition
1. Medium purity
- Liquid can not be filled with dense bubbles in the
- Liquid can not suspend a large number of solid, such as crystal
- Tank bottom can not deposit a large amount of sediment
2. Material of the container to be tested: carbon steel, stainless
steel, various metals, glass, epoxy resin, hard plastic, ceramic,
glass, hard rubber or composite materials
3. Tank type: spherical tank horizontal tank tank vertical tank and
so on
4. Probe installation requirements
- For iron containers, the end face of the probe can be coated with
silicone grease and directly attached to the bottom of the
container with a magnetic chuck. If the container shell is glass and other materials, you can use
glue to stick the probe fixed or fixed at the bottom of the
container with a bracket probe pointing to the measured distance in
the same straight line
- The probe is directly above the coil and other shielding
- Keep away from the liquid inlet at the bottom of the tank to avoid
the impact of the violent flow of the liquid on the measurement
- Keep away from the bottom of the tank top inlet to avoid the impact
of the inlet to affect the measurement of the liquid level
fluctuations
- Higher than the outlet or sewage outlet to avoid long-term sediment
at the bottom of the tank adversely affecting the measurement. If
conditions are not met, measures should be taken to ensure regular
removal of sediment at the bottom of the tank
