DensiCheck TX is an economic answer to the problem of monitoring liquid concentration and density in a wide variety of applications. Available as in-line transmitter in both non-invasive and invasive formats. DensiCheck TX provides a continuous output of concentration to enable processes to be optimised. The result – reduced rework, improved quality and lower costs. Approved for ATEX installation. On applications where a non-invasive instrument is required, Canongate can supply you with a custom designed sensor. These sensors are typically fitted on a flanged or spool piece with a remote connection to the electronics.

APPLICATIONS :

DensiCheck TX is being used in many different industries to measure the concentration of numerous different liquids:
 Acetic Acid
 Beer
 Ethanol
 Glycol
 Hydrogen Peroxide
 Nitric Acid
 Sodium Hydroxide
 Sucrose
 Acetone
 Calcium Chloride
 Ethylene Chloride
 Hydrofluoric Acid
 Isopropyl Alcohol
 Phosphoric Acid
 Soft Drinks
 Sulphuric Acid
 Ammonium Hydroxide
 Chromic Acid
 Ferric Acid
 Hydrogen Chloride
 Methanol
 Sodium Chloride
 Spirits
 Wort

FEATURES :

 Non-invasive and invasive process connections
 High accuracy and repeatability
 ATEX Hazardous area approval
 No moving parts

PRINCIPLE OF OPERATION : 
DensiCheck TX uses the established principal that sound velocity in a liquid is related to concentration. Ultrasound pulses are transmitted through the liquid and reflected to their source. The time of transmission is measured using advanced high speed electronics, and the variation is converted by the on-board microprocessor to a signal representing the liquid concentration. Temperature is automatically compensated for by an integral sensor and the resulting value is transmitted via an analogue or digital signal to a suitable display or host controller.

MODE OF OPERATION :
DensiCheck TX is designed for measuring one or two liquid types at a single process point. For multi-line or multi-product applications, DensiCheck TX can be combined with a separate Display/Control unit to form a DensiCheck 2000 System capable of monitoring up to four lines with 32 different calibrations.
