Abstract
A thickener/clarifier system includes a thickener/clarifier and one or more sensors measuring respective process or operating parameters of the thickener/clarifier(s) during operation thereof. The sensors are operatively coupled via hard-wired connections and possibly via 4-20 mA converters to one or more wireless transmitters. At least one wireless receiver receives the wireless signal(s) from the transmitter(s). At least one display is hard-wire coupled to the receiver(s) for displaying a magnitude of each process or operating parameter measured.
Claims13
A system for separating solids and liquids of a slurry or suspension, said system comprising:
- at least one thickener/clarifier;
- at least one sensor measuring a process parameter or operating parameter of said thickener/clarifier during operation thereof;
- at least one signal converter operatively coupled via a hard-wired connection to said at least one sensor for converting an output signal thereof to a secondary signal of a predetermined coding format;
- at least one wireless transmitter operatively coupled via a hard-wired connection to said at least one signal converter for transmitting said secondary signal as a wireless signal;
- at least one wireless receiver receiving said wireless signal from said at least one transmitter;
- and at least one display operatively coupled via a hard-wired connection to said at least one receiver for displaying a magnitude of said process parameter or operating parameter measured by said at least one sensor.
A system for separating solids and liquids of a slurry or suspension, said system comprising:
- at least one thickener/clarifier;
- a plurality of sensors measuring respective process or operating parameters of said thickener/clarifier during operation thereof;
- a plurality of signal converters operatively coupled via respective hard-wired connections to respective ones of said sensors for converting output signals thereof to secondary signals of a predetermined coding format;
- a plurality of wireless transmitters operatively coupled via hard-wired connections to respective ones of said signal converters for transmitting said secondary signals as respective wireless signals;
- at least one wireless receiver receiving said wireless signals from said transmitters;
- and a plurality of digital display meters operatively coupled via hard-wired connections to said receiver for displaying magnitudes of respective ones of said process or operating parameters measured by said sensors.
A system for separating solids and liquids of a slurry or suspension, said system comprising:
- at least one thickener/clarifier;
- a plurality of sensors measuring respective process or operating parameters of said thickener/clarifier during operation thereof and generating respective output signals encoding magnitudes of said process or operating parameters;
- at least one wireless transmitter operatively coupled via hard-wired connections to said signal converters for transmitting at least one wireless signal carrying said magnitudes in an encoded form;
- at least one wireless receiver receiving said wireless signal from said at least one wireless transmitter;
- and at least one display operatively coupled via a hard-wired connection to said receiver for displaying said magnitudes.
