Excellence the World can Measure In-Line Measurement In-line liquid concentration transmitter General Description DensiCheck TX is a cost effective solution for monitoring the liquid concentration and density in a wide variety of applications. An in-line sensor and integral transmitter, the DensiCheck TX provides a continuous output of concentration to enable processes to be automated and optimised. The result – reduced labour, improved quality of process and lower running costs. Approved for ATEX installation. On corrosive, toxic or hygienic applications where a non-invasive instrument is required, Rototherm Canongate can design a customised solution. 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: Beer Wort Ethanol (Alcohol) Sucrose Soft Drinks Acids Chlorides Sodium Hydroxide Acetone Isopropyl Alcohol (IPA) Glycol Hydrogen Peroxide Ammonium Hydroxide Methanol  Unrivalled accuracy and repeatability  ATEX/IECEx approvals  No moving parts DensiCheck TX uses the established principal that ultrasonic velocity (the speed that ultrasound travels through a liquid) is related to concentration. High frequency pulses are transmitted 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 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. High reliability Increased process efficiency Improved quality process monitoring Rapid payback of investment 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.
