REFRACTOMETERS | 
|
| Patented digital process refractometers for in-line liquid measurements. Used to determine the concentration of dissolved solids by optical measurement of the temperature and refractive index. Patented optical image detection ensures the measurement is not influenced by bubbles, particles, color, pressure, turbulent flow or drifting signal.

CONSISTENCY & DENSITY ANALYZERS | 
|
| Microwave density meters using a new principle of microwave phase difference measurement to determine the density (consistency) of fluids flowing through pipes. This technology is unaffected by flow velocity and reduces the effects from other signal contaminations. There are no moving parts to the meter and not protrusions into the process pipe.
