1 EMCO UniMag TM Magnetic Flowmeters DeltaMass MT Series Mass Flow & Density Sensor 4-24 in. ( mm) The DeltaMass Flowmeter combines a UniMag magnetic flowmeter and a low level gamma ray density sensor in one unique package to accurately measure mass flow of liquids with dissolved and undissolved solids in pipes 4-24 in. ( mm). This flowmeter has no moving parts or vibrating tubes and is easy to service in the field. The encapsulated sensors of the DeltaMass flowtube are mounted in a plane perpendicular to the source and scintillation detector of the integral density sensor. Volumetric flowrate and density measurements are processed in a remote 4411e magnetic flowmeter transmitter and remote X99 microprocessor. The X99 continuously calculates and displays the mass flowrate, density, specific gravity, and % solids in any desired engineering units. These are normally expressed in dry state units, unless otherwise specified. Two isolated 4-20 ma outputs are provided for mass or volumetric flowrate, and density or % solids. Typical DeltaMass applications include dredging and mining slurries, waste treatment sludge, kaolin, lime mud and high consistency pulp.

2 Innovative Sensor Technology has combined their innovative UniMag magnetic flow technology (refer to UniMag DT series flowtube, 4411e and X99 product literature) with an equally innovative ultra low intensity gamma ray densitometer in one compact flowmeter. The DeltaMass MT series flowmeters directly and accurately measure the mass flow of liquids and slurries. system, to the control room. The density signal, I, is related to the media density by the following equation: I = I ref x e µpd The source intensity of the densitometer is so low (microcuries) that no operating license, wipe tests, surveys, or special training are necessary. The user simply provides protection against theft of the device and for disposal of spent material. The densitometer incorporates ultra sensitive scintillation detectors which allow slurry density to be measured with typical accuracy of ± 0.5% of span. The densitometer is comprised of the source, the detector, and a microprocessor transmitter. The low level source sends a collimated beam through the flowtube and process media to the externally mounted detector. The gamma rays are beamed into the flow cross sectional area such that the average density of the slurry is measured. The output of the scintillation detector will respond to changes in the beam intensity due to change in the media density. The beam intensity at the detector will decrease as the media density increases. The signal measured by the detector is communicated to the microprocessor transmitter. The density measured is referenced to a known or standard condition, such as water, or an empty pipe. where I ref is the reference density, d is the inside flowtube diameter, and µ is the radiation absorption coefficient. This relationship is determined by calibration, linearized, and expressed in density or % solids. The mass flowrate, M, is determined by the equation: M = Q x p mix Where Q is the volumetric flowrate determined by the 4411e transmitter incorporated into the microprocessor transmitter, and p mix is the mixture density determined by the densitometer. Alternately, the mass flowrate of the solids, Ms, may be computed. This requires that values for the density of the solids phase, p S, and the density of the liquid phase, p 1, be known. By measuring the density of the mixture Ms can be calculated using: Ms = [ Q x p s x ( p mix -p 1 )] / [ p s -p 1 ] The microprocessor transmitter includes the intelligent electronics for the densitometer, as well as an integral 4411e transmitter used to generate the volumetric flow measurement. The microprocessor transmitter is modular in design and has a menu driven push button configuration. Step by step prompts and instructions aid the user in set-up. A back-lit LCD display provides readout of process information in desired engineering units. The microprocessor transmitter can be installed anywhere from the field location of the measurement The density of the liquid phase and the solid phase can be continuously calculated using algorithms or density vs. temperature tabular data programmed into the microprocessor transmitter. An RTD can be added to the flowtube (as a special feature in the Flowtube Options section of the ordering code) if the process temperature (and therefore liquid and solid phase densities) can vary significantly.

3 DeltaMass Flowmeter Specifications DELTAMASS SYSTEM ACCURACY ± 1% of mass flowrate (or better) typical for a media density variation of ± 20% and > 1.5 fps (0.45 m/s). ± fps (± m/s) for < 1.5 fps (0.45 m/s) Note: For media such as ferric chloride, ferric sulphate (Odophos), high temperature paper mill liquors, lime mud or similar highly conductive media, flowmeter performance can be adversely affected. Please consult EMCO for these types of applications, otherwise performance guarantee is null and void. DELTAMASS SYSTEM REPEATABILITY ± 0.5% of span MEDIA CONDUCTIVITY: > 3 µs/cm DELTAMASS FLOWMETER ENVIRONMENTAL RATING: NEMA 4X and IP65 CABLE TYPE There are 3 separate cables used to the remote 4411e transmitters and 1 to the density meter. 1 cable is for the sensing electrodes, 1 cable for the energizing coils and one cable for the reference coils. Each cable is 2-core, multistranded and overall shielded 2 18 gauge (US) e.g. Beldon #8760 or mm 2. MAXIMUM CABLE LENGTH: 50 feet (15 m) is standard supply. Special order is 100 feet (30 m). MAXIMUM SCINTILLATION TEMPERATURE 150 F (65 C). This sensor is on the outside of the flow tube, which should be thermally insulated as necessary if media temperature is > 150 F. Consult EMCO or authorized representative for more information. GAMMA SOURCE Cesium CS-137 (max. 900 microcuries / 33.3 M Bq) or Cobalt CO-60 (max. 200 microcuries / 7.4 M Bq) gamma source, dependent on application. Levels are so low that a license, wipe tests or surveys are not deemed necessary by the U.S. Nuclear Regulatory Commission. The minimum requirements regarding levels of radiation for this are: 5 mrem/h at 2 from source 0.5 mrem/h at 12 from source Other countries have similar arrangements but the appropriate regulatory agency should be consulted. MICROPROCESSOR TRANSMITTER The X99 microprocessor based transmitter is separate from the 4411e transmitter. All electronics are contained in NEMA 4X enclosures. Refer to separate data sheet for more information. Differential Specific Gravity (S.G.) Selection The gamma ray source selection is dependent on the flowtube size and the differential ( ) specific gravity range that is to be measured. The S.G. is calculated by subtracting the minimum S.G. value from the maximum S.G. value of the media being measured. The DeltaMass selection code shown in the table below is used in the order code to specify the Differential S.G. selection. Please also advise a) Dry Solids S.G. Range, b) Maximum % Dry Solids.

(150 mm) flowtube has a specific gravity between 1.4 (minimum) and 1.8 (maximum), making the D S.G. 0.4 (= ). The above table indicates either the small or large span could be used for this example for a 6 in. flowtube. You should always select the large span option over a small span if both are applicable because the large 4 to 8 in. (100 to 200 mm) DeltaMass Flowmeters span option has a lower list price. Hence, you would select option (B) for the differential S.G. selection in the ordering code to measure a D S.G. range of 0.4 for a 6 in flowtube.
