Inline density and concentration meters for slurry, chemicals and process liquids — built in Xi'an, China, and running in mining, power, chemical and dredging plants worldwide.
Our flagship PS7000 measures slurry density by ultrasonic acoustic impedance. Because it reads a material property rather than a radioactive count rate, it needs no source, no licence and no disposal route at end of life — across DN50 to DN1000.
| ps7000-modbus | Read-only Modbus RTU register map, with working Python and C# clients. Machine-readable JSON and CSV. |
| ps7000-hart | HART 5 command set, device variable map and status decoding. |
| pisonics-docs | Current English datasheets for PS7000, PS7010 and PS7020 — CC BY licensed, so you can drop them straight into a tender package. |
| density-calc | Slurry concentration and dredge production maths — Cv, Cw, dry tonnes per hour, bank volume. |
Integrating a meter into a PLC, DCS or historian? Start with ps7000-modbus — the register map is generated from a single source of truth and the decoder is unit tested, so the parts that usually cost a day (32-bit word order, the off-by-one on register numbers) are documented rather than left to be discovered on site.
