Frequently Asked Questions

1. How do I place an order?

For clients in Canada, US,  South America and Europe, orders can be placed directly through SyncroCraft, LLC in the US.   For clients in Asia, orders can be placed through Shinka Industry Co., Ltd.

2. What is the lead time?

The standard lead time is 2 weeks after receipt of order.

3. What is the warranty?

The Sonic Meter is warranted against manufacturing defects for 12 months from time of purchase.   We are dedicated to expediting repairs.

4. What are the recommended Calibration intervals?

Calibrations are recommended every 12 months.   For large volume tank lines and frequent monitoring, we recommend calibration every 6 months.   The lead time for calibration service is 3-5 working days.

5. Does the Sonic Meter have a CE Mark?

The Sonic Meter has been CE tested and certified by ITS.

6. Is the Sonic Meter NIST Traceable?

Our meters are calibrated with NIST traceable instrumentation.  We recommend annual calibration.  For high use (daily), we recommend bi-annual calibration.

7. What is the diameter and length of the probe?

The probe diameter is .312″ (8mm) and the length is 15″ (38cm).

8. What is the effective length of the probe, i.e. what is the sensed length?

The effective length of the probe is approximately 13-14″ (33-36cm) depending on how you hold or mount it.

9. What is the sensor tip diameter relative to the probe body diameter?

Sensor diameter = 0.2″ (5mm), probe diameter = 0.312″ (8mm) for standard probe.

10. Are Custom Probe sizes available?

We can build longer probes up to 36″ (1m). The lead time for custom probe work is 4-6 weeks.  We will also review concepts for angled probes or other non-standard geometries.

11. What is the minimum immersion depth in order to get reliable data with your probe?

The face of the probe has to be immersed in the fluid.  The surface of the liquid is in motion with standing waves.  You need to have the tip below the standing waves in order to make reliable measurements. The tip must always be in contact with the solvent.

12. How does your meter compare to others on the market?

The Sonic Meter is extremely well constructed.  The probe is stainless steel with a metal BNC electrical connector.  The probe is hermetically sealed by laser welding to the probe body.  The probe uses an all metal construction.  We do not use glass, plastic or rubber in the construction of the sensing element of the probe.  The Sonic Meter uses a piezo sensor with sensitivity in units of pressure (psi). We don’t know of a piezo transducer with a sensitivity that produces units of Watts/cm2 or Watts/gal?  We are wary of measurement devices using non-scientific units or which allow the user to re-calibrate.  The calibration of our meter is controlled and performed under a standard protocol using calibrated tools.  The output is expressed in pressure units because piezo elements are pressure sensitive devices.  The cavitation of the liquid applies forces to the total area of a part being cleaned.  The Sonic Meter probe senses these forces over its sensing area.  With the Sonic Meter, you will be able to map and quantify the pressure distribution of your tanks

Tank manufactures specify their power output in Watts/gal.  The Watts/gal output is determined by measuring the power used to drive the piezo transducer.  The measured power is then divided by the tank volume.  The tank manufacturers do not have a direct tank measurement for the resultant energy density.  There is one test used by manufacturers to test tank functionality, the ceramic ring test.  This test uses carbon coated ceramic rings as an indicator of how well the ultrasonics are cleaning by how much carbon is removed over some specified time period.  This test, usually performed by a field technician, is used to determine whether or not an older tank’s ultrasonics are working properly.  The ceramic ring test is qualitative, a “go-no-go” type of test.

When tanks fail they either don’t work at all or the transducer output begins to degrade.  The Sonic Meter will be indispensable for determining when the latter takes place.  With true sensitivity to fluid cleaning-forces as a result of cavitation, our product is the only cavitation meter that is driven by standard engineering units and NIST traceability.

13. How can the probe detect power differences for small movements of 1-10mm?

In high quality tanks, you will not notice any significant difference over a 1-2mm translation of the probe.  However, beyond 5mm translations or depth changes, significant changes in pressure readings can be measured.  The pressure can be much higher than your tank’s average and can be concentrated in regions of the tank. Hot and cold areas of high and low cavitation scrub force can be detected with the Sonic Meter.  These areas become more pronounced when parts and racks are placed in the tanks or when tanks’ geometries have non-uniform shapes.  Optimizing locations and quantifying them with the Sonic Meter will increase the precision and control of your cleaning process.

14. If parts to be cleaned influence the energy distribution in a tank, what effect does your measurement probe have on the tank’s energy distribution?

Several factors can produce regions where pressure is significantly higher or lower when compared to your tank’s average pressure (average means at least 10-20 readings at 1 or more depths).  The probe does not represent a significant volume which would alter or influence the pressure distribution.  Some tanks have shapes with reliefs for filters, heaters, basket hanger, etc.  In and around many of these regions, the pressure can vary more than in the general rectangular work volume.  With the Sonic Meter, you should probe around the areas of your tank where there are discontinuous sections in the tank’s walls.  You will observe slight to significant changes in pressure when compared to your averaged readings.  The pressure will always be more varied near the surfaces of the protruding geometries, corners and edges.

15. Have you ever measured the effectiveness of procedures to degas a tank, i.e. have you ever measured the % oxygen or nitrogen in an ultrasonic tank?

We have not done any experimentation with degas times or % oxygen/nitrogen since there are several other variables that are specific to each tank and the specific process parameters.  Therefore, it is important to develop your own process protocol for optimization by quantifying variables that affect tank pressure output.  The Sonic Meter is the indispensable tool for this type of process optimization.

16. Can probes be switched to different meters?

Yes.  However, each probe has a unique sensitivity.  The meter needs to know this sensitivity in order function properly.  We set the probe’s unique sensitivity value in the meter’s digital memory so that the displayed output has been correctly compensated for in the signal processing.  Probe sensitivity range is usually between 28-34 mV/psi.  The sensitivity does not change after the sensing element is manufactured. The procedure for changing the sensitivity when you switch out a probe with another is described in our manual. However, we recommend factory re-calibration of the probe to the meter when switching out a probe.
