WL705 Ultrasonic Water Level Sensor
[attachment=51214]
Description
The WL705 uses the latest ultrasonic distance measuring
technology for accurate non-contact water
level monitoring. The sensors contain a rugged
transducer in a stainless steel sealed housing for long
life and provides an industry standard 4-20 MA output.
There are three ranges available including 3 ft, 12 ft, and
48 ft to meet a wide variety of applications. The unique 3
ft range sensor is ideal for measuring flow in small flumes
and weirs. The 12 ft and 48 ft ranges are best for
measuring river, lake and tank levels and for measuring
open channel flow in larger flumes. Installation is simple
and requires no programming or calibration. No
maintenance is required.
• Long range, short dead band
• Unaffected by optical factors like color and
transparency
• 4-20 ma Transmitter
• Durable sealed housing for wet or dirty
applications
• For monitoring water level in tanks and
open channel
Specifications
Ranges: 0.33 to 3 ft; 0.33 to 12 ft; and 1 to 48 ft
Resolution: 0.009 in, 0.035 in, and 0.141 in
Repeatability: Greater of ±0.03 inches (0.76 mm) or 0.1% of
range @ constant temperature
Accuracy: Better than 0.5% of range @ constant temperature;
affected by temperature gradients, target echo strength, and
speed of sound in vapors
Transducer Type: Ruggedized piezoelectric
Beam Angle: 12° conical shaped pattern
Power:
3 and 12 ft range: 10 to 30 VDC @70 mA max
48 ft range: 10 to 30 VDC @40 mA max
Output: 4-20 mA (4 mA is minimum water level and 20 mA is
maximum water level)
Update Rate: 50 ms
Operating Temperature: -40 to 158°F (-40 to 70°C)
Humidity: 0 to 100% (avoid heavy condensation)
Housing Material: 303 stainless steel
Dimensions:
3 and 12 ft rng: 4.062 in. long x 1.05 in. dia. (103.2 L x 26.7 Dia mm)
48 ft range: 4.75 inch long x 2.375 inch dia. (121 L x 60 Dia mm)
