Atrato Flow Meter: Titan Miniature Ultrasonic Low-Flow Liquid Sensors
Quick Answer: The Atrato flow meter by Titan Enterprises is a miniature ultrasonic sensor for low-flow liquid measurement. It handles flow rates from 0.002 to 2.0 L/min with strong repeatability for clean and low viscosity liquids. Silver Automation Instruments can supply a compatible low-flow ultrasonic meter or a direct replacement based on your process data.
The Atrato uses ultrasonic transit time technology. It measures clean liquids with low viscosity. Many engineers choose this sensor for dosing, laboratory test rigs, and chemical injection. The body is compact and fits inside small panels where larger mechanical meters cannot work.
Atrato Flow Meter Technical Parameters
Standard Atrato models cover a flow range from 0.002 to 2.0 L/min. Accuracy is about ±1 percent of reading. Repeatability is ±0.1 percent. Operating pressure is up to 10 bar. Wetted parts include PEEK, 316 stainless steel, and EPDM or FKM seals. Output options include 0 to 5 V pulse, 4 to 20 mA, and RS232. Power supply is 5 to 12 V DC. Process temperature range is -10 to 60 degrees Celsius.
These numbers matter when you build a dosing skid or a test bench. A DN15 electromagnetic flowmeter cannot resolve such small flow rates. The Atrato type sensor fills that gap. But the sensor is not for dirty water or slurries. It is also not for high viscosity fluids above 100 cP without testing.
Typical Low-Flow Liquid Applications
We have seen this type of meter on customer sites many times. A paint manufacturer in Vietnam used a low-flow ultrasonic meter for solvent dosing. A seawater desalination plant in Oman required a precise meter for antiscalant injection. Food and beverage plants in Australia use these sensors for flavor additive dosing. Pharmaceutical labs in Malaysia measure buffer solutions at 0.1 L/min.
In practice, the meter works well for clean water, deionized water, solvents, and light oils. For corrosive liquids, check the wetted materials before ordering. For hazardous area dosing, Silver Instruments can supply ATEX Zone 1 certified flow meters with 4 to 20 mA HART output.
Silver Instruments Low-Flow Meter Options
Silver Automation Instruments offers low-flow ultrasonic flow meters for similar tasks. Our range covers clean liquids, low viscosity fluids, and small line sizes from DN4 to DN15. We supply 4 to 20 mA HART output, pulse output, a
Here is the thing. Most engineers skip this part and compare only price. The total cost includes sensor replacement, cleaning time, and calibration drift. A low-cost meter with poor repeatability causes scrap or rework. A paint manufacturer in Southeast Asia learned this after replacing three cheap sensors in one year.
How to Specify a Low-Flow Meter
Tell us your exact process conditions. Send us your pressure in bar, temperature in degrees Celsius, pipe size in DN, and flow range in L/h or kg/h. We will recommend a low-flow ultrasonic meter or a Coriolis mass meter. We can also quote a drop-in replacement for the Atrato flow meter if you send the full model code.

Low-Flow Ultrasonic Flow Meter FAQ
Question 1: What is the minimum flow rate the Atrato flow meter can measure?
Answer: The Atrato can measure down to 0.002 L/min depending on liquid viscosity and tube size. For very low flow below 0.001 kg/h, a Coriolis mass meter is more suitable.
Question 2: Can the Atrato flow meter handle dirty liquids?
Answer: No. The Atrato is designed for clean liquids with low viscosity. For wastewater or slurries, use an electromagnetic flowmeter or a clamp-on ultrasonic meter.
Question 3: What output signals does the Atrato flow meter support?
Answer: It supports pulse output, 0 to 5 V, 4 to 20 mA, and RS232. If you need HART or Modbus, Silver Instruments can supply an alternative ultrasonic meter with 4 to 20 mA HART and RS485 Modbus.
Question 4: Is the Atrato flow meter suitable for high pressure systems?
Answer: Standard Atrato models operate up to 10 bar. Check your process pressure before ordering. For higher pressure, specify a stainless steel body or choose a different sensor.
Question 5: How do I get a price for an Atrato flow meter replacement?
Answer: Send us the model code, flow range, pipe size, pressure, temperature, and liquid type. Silver Automation Instruments will provide a quote within 24 hours.
