AT600 Flow Meter: Panametrics AquaTrans Transit-Time Pipeline Transducers
Quick Answer: The Panametrics AquaTrans AT600 flow meter uses transit-time ultrasonic technology to measure clean liquid flow. It works with clamp-on or wetted pipeline transducers from DN15 up to DN3000. Silver Automation Instruments supplies the transmitter, transducers, cables, and field support for water plants, chemical lines, and food processing systems.
This guide explains transducer selection, signal wiring, installation rules, and pricing steps for the AT600.
How the AquaTrans AT600 Transit-Time Meter Works
Two transducers send and receive ultrasonic pulses through the liquid. Flow speed changes the transit time difference. The transmitter converts that time difference into flow rate and total flow. Because the method does not need magnetic coils, the meter works on demineralized water and other low conductivity liquids. So it is a practical replacement for magnetic flow meters on demineralized water.
Most units measure clean liquids with low solids and low gas bubbles. The meter handles many clean liquids up to 100 cP if the flow profile is fully developed. For dirty or two phase flow, an electromagnetic flow meter may be a better fit. In practice, engineers choose the AT600 for reverse osmosis lines, cooling water, boiler feed water, and clean chemical transfer.
Pipeline Transducer Selection and Pipe Sizes
Silver Instruments selects the transducer after checking pipe material, wall thickness, liner, and flow range. Wetted transducers work well from DN15 to DN50. They give better low flow response on small lines. Clamp-on transducers cover DN80 to DN3000 without cutting the pipe or stopping the process.
For a DN150 stainless steel line carrying RO water at 25 °C, we quote the AT600 with clamp-on transducers and a PT100 temperature input. The transmitter sends flow rate in m3/h and total flow in liters. A customer in Vietnam used this setup on a packaging water line and connected the 4-20 mA HART signal to a Siemens PLC.
Output Signals and PLC Integration
The AT600 supports 4-20 mA analog output with HART. It also has pulse output and relay alarms depending on the configuration. Most plants wire the analog signal to a PLC or SCADA and keep HART for remote diagnostics. Some sites also use Modbus or Foundation Fieldbus gateways.
The transmitter reports volumetric flow in m3/h. For mass flow in kg/h, pair the AT600 with a flow computer or a PLC density calculation. The 4-20 mA loop can send flow rate or totalizer pulse.

Installation Notes That Prevent Most Startup Issues
Install the transducers on a full pipe section with straight run. For clamp-on transducers, allow 10D upstream and 5D downstream where possible. Clean the pipe surface to bare metal. Apply coupling compound evenly. Avoid downward pipes that may run partially full. Avoid pump discharge with heavy cavitation.
Measure pipe wall thickness with a UT gauge before programming the transmitter. Most engineers skip this part. Then they call us from site because the meter reads zero or drifts. If the pipe has internal scale or liner, tell us before shipment. We can adjust the transducer frequency and mounting fixture.

FAQ
Can the AT600 measure demineralized water with low conductivity?
Yes. The transit-time method does not need conductivity. It works with clean liquids from 0 µS/cm upward if solids and gas content are low.
What pipe sizes does the AT600 support?
Pipeline transducers cover DN15 to DN3000. Wetted transducers suit small lines. Clamp-on transducers cover larger pipes without cutting or process shutdown.
What output signals are available?
Standard options include 4-20 mA with HART, pulse output, and relay alarms. Some configurations include Modbus or Foundation Fieldbus.
What is the typical accuracy?
Clamp-on installations can reach ±1% of reading with proper straight pipe and wall thickness input. Wetted transducer installations can reach ±0.5% of reading after calibration.
How do I get a quote from Silver Instruments?
Send us pipe size in DN, liquid type, temperature, pressure, flow range, and output preference. Our team will return a model selection and price.
