Ultrasonic spray utilizes ultrasonic energy to break liquid and form a few micron drop size. The ultrasonic spray nozzle can use low vibration energy to make liquid atomized via gravity and low-pressure compressed air.  MSK-SP-01A is a 130 W, 40 kHz ultrasonic spraying nozzle with a power controller for DIY, low-cost spray pyrolysis coating in the material research lab. (Updated with digital current meter and KF25 adaptor since July 27, 2015)

Ultrasonic Generator	Input power: 208 - 240 VAC,  50/60 Hz (A transformer can be used for 110 V) Ultrasonic output: 0 - 130 W adjustable. Three levels (1, 2, 3) that is corresponds to current value of 0.05, 0.06-0.07, and 0.08. Ultrasonic frequency: 40 kHz (constant)
Ultrasonic Converter	PZT (piezoelectric zirconate titanate crystal) Diameter: 25 mm
Converter Cable Length	2.5 m (8.2 ft)
Spray Nozzle	Two Spray nozzles made of Titanium alloy (Ti-6Al-4V) with KF-25 Adapte (click left picture to see details) One cylindrical type - provides a narrower spray pattern with ~2 cm diameter One cone type - provides a wider spray pattern ~ 4 cm diameter KF25 quick clamp is included to connect the spray head to the KF25 port  Max. temperature: 70 °C Volumetric flow rate: Q= μ*A*(2P/ρ)0.5   Flow Velocity: W= μ*(2P/ρ)0.5\    μ is  flow rate coefficient,  A = πd2 / 4 - Nozzle sectional area; P is hydrostatic pressure, ρ is solution density.     μ = 0.62 - flow rate coefficient for the hole;    μ = 0.83 - for nozzle with sharp inlet edge (figure I);    μ = 0.97 - for nozzle with smooth inlet edge (figure II);    μ = 1.15 - for cone nozzle with smooth inlet edge (figure III). Nozzle taper 7° < β < 12°.        Spraying speed:  5 mL/min~ 40 mL/min (0.3L/hr -  2.4L / hr.) Fluid viscosity range: 1 - 100 mPa·s (cP) Customized nozzle shape is available upon request at extra cost.
