1) PISTON GAUGE:- Highly cost effective and rugged, robust, design.
- Most suitable for general purpose applications, usually for liquids where small migration between high and low ports is permisible.
- Uses a piston with teflon cup seal as a sensor to separate high and low pressure in response to pressure differential.
- Recommended where line pressure and differential is high.
- Available with in-line, bottom and back porting.
- Standard materials: Aluminum and SS-316.

2) ROLLING DIAPHRAGM GAUGE:- Operates on rolling diaphragm as sensor which separates high and low pressure ports.
- Recommended for air and gas application or where zero migration of fluid between high and low ports is important.
- Useful for high line pressure and differential pressure range up to 100 PSID.
- Can also be used for dissimilar fluids as there is no fluid migration between high and low pressure ports.
- Available with in-line, bottom and back porting.
- Standard materials: Aluminum and SS-316.

3) CONVOLUTED DIAPHRAGM GAUGE:- Operates on convoluted diaphragm as sensor which separates high and low pressure ports.
- Recommended for air and gas application or where zero migration of fluid between high and low ports is important.
- Useful for high line pressure and differential pressure range up to 60 PSID.
- Can also be used for dissimilar fluids as there is no fluid migration between high and low pressure ports.
- Available with in-line, bottom and back porting.
