ChannelFlo™ OCRM Flocorp


Guided Wave Radar Open Channel Flow Meter

The ChannelFlo™ OCRM flow meter is an all-in-one solution preconfigured for open channel flow. The Tracer 1000 radar level meter and DigaTouch/eXmod display are coupled together to form the OCRM meter. As a stand alone meter, the Tracer 1000 has range of 2 inches to 65 feet and a 4-20mA output. Easy mounting and a one-piece feed through makes this a rugged sensor that can withstand up to 302°F and 580 PSIG pressure. Remote email alerts and data logging make this meter a wise choice for remote locations as well.

Features & Benefits

  • Revolutionary TDR Technology
  • High accuracy (+/- 0.12mm) with NO moving parts
  • Dead Band (Top & Bottom) 1.5”
  • Probe guided radar impulses for ease of flow measurement in narrow channels
  • Isolated 4-20 mA, 4 10A relay outputs and 1 PNP transistor output plus RS-485 Serial communication, and Ethernet communication
  • 6 digit red LED display with touch screen interface and remote monitoring/configuration software (included)


Electrical Specifications 




Measuring Range [M]

Probe length [L] less both inactive

areas at top and bottom [l1  and  l2]  in this range Tracer 1000™ will have the specified measurement  performance.  It  is recommended that the maximum and minimum liquid levels to be  measured  are within the measuring range [M] of the sensor.



Output Functions

Continuous level measurement through analog output and point level detection through switching output. 




Analog Output (Active)

Current output 4-20mA: The span between the lower range value [4mA] and the upper range value [20mA] is equal to 0-100%    of the continuous level measurement reading. It is recommended that the span between those two range values stays within the measuring range [M]. 
Application Specifications 
Dielectric Constant [ɛr]


316 SS Rod: > 1.8

ConductivityNo restrictions 




Total Load Resistance

< 500Ω: HART resistor approx. 250Ω

+ load resistance approx. 250Ω if the current output is connected to a device with an inner resistance of approx. 250Ω, then there is no additional, external HART resistor necessary. In that case, the HART modem is connected in parallel to the current output wires.

 DensityNo restrictions 
Dynamic Viscosity316 SS Rod: < 5.00mPa s = 5.000cP 
Standard Application Temp.F: -40º to 302º C: -40 to 150º 
Ambient TemperatureF: -13º to 176º C: -25º to 80º 
Application Pressure-14.50 PSI to 580 PSI 
Lower Range Value4.0mA (span 0%) 
Upper Range Span20.0mA (span 100%) Velocity of Level Change


< 3.2 fps

Response Time0.5s (default), 2s 5s (selectable) 




Interface (i.e. oil on top of water)

An oil layer of < 2.8” thickness on top of water is not detected by the sensor;  in this case the sensor will detect only the water level at a slightly lower position  than actual. From an oil layer thickness > 2.8” onwards, the sensor detects the total level, including the oil layer, according to specifications. 
Temperature DriftLess than .0078 in/ºF change in ambient temperature 
Switching Output DC PNP (Active)NC (default) or NO (short-circuit protected) 
Load Current< 200mA 
Supply Voltage12-30VDC (reverse-polarity protected) 
Mechanical Specifications 
Current Consumption< 50mA at 24 VDC (no burden)
