Echotel® Model 300/301 Ultrasonic Non-Contact Transmitter For Level, Volume, and Open Channel Flow

DESCRIPTION

The Model 300/301 is a full-featured, powerful ultra- sonic system for measurement of liquid level, volume, or open channel flow. Available as an integral or remote mounted transmitter, this extremely versatile system is simple to install and calibrate. The non- contact design means that it is not affected by changes in specific gravity, viscosity, or conductivity.

FEATURES

  • Isolated 4–20 mA output includes an active/passive mode for loop power or device power.
  • RS-485 with Modbus protocol allows bi-directional communication with DCS or PLC.
  • Two or four 10 amp SPDT gold flash relays provide flexibility for most alarm and control schemes.
  • 16-button keypad and two-line, 16-character LCD alphanumeric display.
  • Temperature compensation integral to ultrasonic transducer.
  • Output in units of level, volume, or open channel flow.
  • Most common flumes and weirs preprogrammed in memory in addition to the Manning formula and a custom table using either a linear or spline curve.
  • Complete self-diagnostics checks all relays, outputs, and system functionality.
  • Class I, Div. 1, Groups B, C, and D on both the transmitter and transducer.
  • QuickCal mode allows complete system calibration in 90 seconds.
  • Powerful 38 kHz EchoMaster™ ultrasonic transducer performs in difficult applications.
  • Password protection prevents unwanted tampering with configuration data.

MEASUREMENT RANGE EXPECTATIONS Ultrasonic non-contact devices are typically rated for a maximum range in ideal conditions. Experience has shown that maximum range must be adjusted for cer- tain factors. Although the maximum range rating is somewhat conservative, each application must be evaluated for specific conditions. The operating parameters listed below can impact the maximum range of measurement:

  • Surface agitation
  • Vapors and steam (as measured by temperature difference between liquid and air)
  • Beam spread interference
  • Sensor alignment
  • Foam
  • Dust
  • Air movement
  • Ambient temperature
  • Pressure HOW TO CALCULATE To estimate how successful a particular application may be, using the chart on page 3: 1. Select one condition from each of the operating parameters that best describes your application. 2. Enter the corresponding performance multiplier value in the application column. 3. Multiply all values together. 4. Obtain the maximum range from the table below that corresponds to your switch or transmitter model. 5. Multiply step 3 by step 4; this yields a value that is the maximum allowable measurement range for this application. Example: The vessel is a closed-top tank, uninsulated, 22 feet tall. Surface agitation: Expect slight agitation from fill line. Performance multiplier 0.9 Vapor and steam: The process temperature is +130° F; slight vapor is expected. Performance multiplier 0.9 Beam interference: No interference exists. Performance multiplier 1.0 Sensor alignment: The sensor will be perpendicular to the liquid surface. Performance multiplier 1.0 Foam: None. Performance multiplier 1.0 Dust: None. Performance multiplier 1.0 Air movement: None. Performance multiplier 1.0 Ambient temp.: 0 to +120° F . Performance multiplier 1.0 Pressure: Atmospheric pressure. Performance multiplier 1.0 Will the Model 300 work for this application? Calculation: Multiplied values of all application columns: 30 feet (maximum) = 24.3 feet The calculation yields 24.3 feet as the new maximum range. Since the tank is 22 feet tall, this application will give satis- factory results. NOTE: The performance estimates provided are conserva- tive estimates. Since these factors are subjective, the estimates have been designed to provide very high confidence of system success. Contact the factory if there are any questions concerning the interpretation of any of these values. Sensor alignment Temperature Pressure Beam spread interference Beam spread interference Air movement Dust Vapors Foam Surface agitation MEASUREMENT RANGE CALCULATIONS

MEASUREMENT RANGE CALCULATIONS SURFACE AGITATION: Surface agitation or waves can degrade the performance. Moderate agitation results in only slight degrada- tion of performance. The worst case is when the surface is a good reflector, but in the wrong direction. (Refer to sensor alignment.) VAPOR AND STEAM: Vapors in the air space, above the process, become apparent, and cause problems when the liquid process temperature is well above the temperature of the airspace. The greater the difference, the more expected vapor problems. The problems result from condensation or layering in the sound path, both of which attenuate the sound signal, degrading performance. Avoid steam if possible. To avoid these problems, ensure that the vessel is insulated so that vapors are less likely to condense. If a vent is used, be sure that the vent, which is where condensation will form, is well away from the sensor. BEAM SPREAD INTERFERENCE: It is strongly recommended that nothing be allowed within the sensor’s beam, except the liquid which is being monitored. Often, the signal from the liquid will be strong, compared to the signal from other sources, such as, ladder rungs filling process material, support struts, etc. For that reason,some applications may provide satisfactory results, even with than 60 interference. Interference from agitator blades is only an intermittent interference that usually has little effect on perfor- mance. It is recommended there be no interference within the 6° half angle of the sensor beam. If interference is unavoidable, make the inter- ference as far as possible from the sensor so that the real signal at the longest distance is stronger than the interference signal. SENSOR ALIGNMENT: Optimum performance is obtained when the sensor is perfectly aligned. If the process is not perpendicular to the sound beam, the sound will not reflect properly back to the sensor. The effect is significant. FOAM: Even small thicknesses of foam can attenuate the ultra- sound and render the system inoperative. If possible, moving the sensor to an area in the tank where there is less foam, will improve the performance. Thick, heavy density foams can sometimes pro- duce a reflection from the top of the foam. The multipliers shown at right are general guidelines. For further assistance consult the factory. DUST: Dust attenuates the sound and results in poor performance. Even barely perceptible haze in the air can cause significant attenuation. AIR MOVEMENT: The movement of air, as possible in an open top vessel, can create a layer from which the sound will reflect. This will be most noticeable in applications where vapors or steam tend to form. AMBIENT TEMPERATURE: The ambient temperature can have a significant effect on the sound and on the sensor’s capability to transmit and receive sound. The most noticeable effect on the sensor is at the temperature extremes. PRESSURE: Sound requires air molecules to be able to travel. Sound will not travel in a vacuum. Likewise, higher pressures will allow the sound to continue without decay, which can cause prob- lems with multiple echoes.
