Ultrasonic sludge level meter - split type with small blind zone

Ultrasonic sludge level meter, ultrasonic sludge interface meter, ultrasonic depth sounder, split type with small blind zone     

1. Introduction     

Small blind zoneUltrasonic Sludge Level Meter, Ultrasonic sludge interface meter, ultrasonic sludge-water interface meter are designed for shallow water pools within 2m. The sensor can operate when immersed 5-10cm in water, with a blind zone of 0.1-0.15m. It uses ultrasonic emission and echo analysis of suspended solids in water to determine the height of the sludge layer.

2. Technical Parameters

Note: This series of ultrasonic probes can also be customized according to customer requirements: high-pressure resistant, high-temperature resistant, small-diameter, small-blind-zone and other special probes.

3. Product Advantages

1> Physically fully sealed probe: one-piece cast seamless probe, service life increased by 1-2 years

 2> Unique probe design: selecting different probes can adapt to low, medium, and high turbidity water quality.

 3> Advanced echo tracking algorithm: can effectively capture true echoes in noisy underwater noise

 4> Multiple compensation modes: built-in temperature compensation, with temperature indication, sound velocity correction mode

 5> Dot-matrix LCD, Chinese/English menu: makes commissioning and application easier, can display multiple graphics

 6> Flexible measurement modes: two measurement modes, level and distance, allow flexible setting of the reference position

 7> Programmable relay output: relays are programmable, each relay can be set to high-level, low-level alarm or off

4. Application Scope

Small blind zone ultrasonic sludge level meter, ultrasonic sludge interface meter, and ultrasonic sludge-water interface meter are designed for shallow pools within 2 m.

The Sensor can operate when immersed 5-10cm in water, with a blind zone of 0.1-0.15 m. It uses ultrasonic emission and echo analysis of suspended solids in water to determine the height of the sludge layer.

Applied in any container with a liquid/solid two-phase interface. Main applications include:

Water plant: sedimentation tank;
Wastewater treatment plants: primary sedimentation tanks, secondary sedimentation tanks, thickening tanks, SBR process hydrolysis tanks;
Coal washing plants: sedimentation tanks;
Power plants: ash slurry sedimentation tanks;
Mining plants: thickening tanks;

Others: oil/asphalt separation tanks; pulp tanks; beverage water clarification tanks; mining clarification tanks; brine tanks; slurry tanks;

VI. Parameters Required for Selection

1. The type of medium to be measured: liquid or solid.
If liquid: whether the liquid surface has steam, mist, foam, waves, agitation, or floating debris;
If it is solid: is there dust?

2. Medium minimum to maximum temperature, minimum to maximum pressure.

3. Corrosiveness of the medium. If placed in a tank, need to know the tank material and whether there is a corrosion-resistant liner.

4. Whether explosion-proof and corrosion-resistant are required.

5. Measuring range in meters, and required blind zone.

6. Working environment: e.g., open tank, covered tank, horizontal tank, vertical tank, spherical tank, whether the tank is at atmospheric pressure, etc.

7. Operating Voltage: 24VDC or 220VAC .

8. Output Signal: 4～20mA current, 485 communication output, or relay output.

9. Device form: Split type.
