AM0 ADDITIONAL FUNCTIONS Liquid Damper (type AM D) A damper is to be provided for steam and gas applications to prevent vibration of float. A damper pot is provided at the bottom of tube part in which damper liquid (silicon or diflon oil) is contained. The friction between damper liquid and damper makes the float movement smooth for stable indication and durability of moving part. Damper is also recommended for liquid application with heavy pulsation. Available types are AM (bottom sidetop side), AM (leftright) and AM 7 (rightleft).(refer to Fig.) Cooling fin (typeam F) A cooling fin is to be provided between tube part and indicator housing to release fluid heat in case fluid temperature is more than o C. Cooling fin is available for models AM (bottomtop side), AM (Bottom sidetop side), AM (leftright) and AM 7 (rightleft), (Refer to Fig.) Fig. Gas Damper (type AM Du) Gas damper is available for gas measurement application which does not require damper liquids.(gas dampers are available for metallic flowmeters only.) Mechanical damper is integrated at the part of float guide which consists of piston and cylinder. (Fig.) As it is not required to install liquid damper at the bottom of flowmeters, it contributes to increase the flexibility of piping design. Also it is not required to fill damper liquid that saves maintenance labour works. Gas damper is applicable for gas measurement applications and not suitable for liquids and steam. Also chlorine gas (easy to form chemical compound) and gas containing rust, trash and oil may hinder the function of piston part. Consult factory for details. Available size is mm to mm ( for mm) and Only for metallic material (Not for lined material). Steam jacket (typeam JS;Semi jacket AM JF;Full jacket) Heating jacket is available for the application of high viscosity and/ or sticky fluids.semi jacket covers tube part only and full jacket covers flanges as well.steam inlet/outlet is screw connection (Rc or NPT). Heating jacket is available for AM (bottomtop) and AM (bottomtop side). Only lbs rating is available for full jacketed flowmeters (AM JF). TGF9E Fig. TOKYO KEISO CO., LTD. 7

Selection of meter size Maximum possible flow rate for each meter size is shown in dimension tables from p. to These figures are based on water flow (Sp. Gr. 0 and Viscosity 0 cp). If actual fluid condition is different from such figures, a conversion calculation is required as following formula: QW = Q (9/ (7/ ) ) Where Qw : Water converted flow rate (m /h) Q : Flow rate of actual fluid (m /h) γ : Specific gravity of actual fluid (no dimension) Example Fluid : Alcohol Sp. Gr. : 0. Flow rate : m /h Flow meter to be used:am QW = (9/ (7/0.)) = 0. = (m /h) Referring to table on p., the required meter size is mm. For possible connection flange sizes, refer to "Table 7" b. Viscosity limit In case the Viscosity of fluid is more than cp, confirm the suitability by Fig. below. Trace viscosity and flow rate and confirm the crossing point is below the curve. If the crossing point is above the curve, consult factory for detailed calculation by computer. Viscosity curve Fig. TOKYO KEISO CO., LTD. TGF9E

Fig. Gas application Generally, flowmeters with damper (type AM Du, AM Du, AM Du, AM D, AM D and AM 7D) are recommended for gas application to prevent float vibration. a. Selection of meter size Maximum possible flow rate for each meter size is shown in dimension tables of AM Du, AM Du, AM Du, AM D, AM D and AM 7D flowmeters If actual fluid condition is different from such figures, a conversion calculation is to be performed by the following formula: QA = Q 0.0 (7+t) / (0+p) Where QA : Converted flow rate in air 0 o C, atm(nm /h) Q : Flow rate of gas to be measured (Nm /h) γ : Specific weight of gas to be measured (Kgf/Nm ) t : Operating temperature ( o C) p : Operating pressure (Kgf/cm G) Example Gas to be measured Nitrogen (N) Specific weight (γ) Kg/Nm Operating pressure (p) Operating temperature (t) Flowmeter to be used Kg/cm G o C AM D Fig.7 QA = 00 0.0 (7+)/(0+) = 00 0.0 9 = (Nm /h) Referring to Table on p. 0 the suitable meter size is mm. For possible connection flange sizes, refer to "Table 7". Steam application Flowmeters with liquid damper (type AM D, AM D and AM 7D) are recommended for steam application to prevent float vibration. Also a cooling fin is normally needed because of high temperature. a. Selection of meter size Steam flow rate is to be converted into water flow rate by the following formula for size determination; QW = Qs 0.0 Where QW: Water converted flow rate (m /h) Qs : Steam flow rate (m /h) γ : Specific weight of steam (Kg/m ) Example Fluid Saturated Steam Pressure 9Kgf/cm G Flow rate t/h Flowmeter to be used AM D First, specific weight of the steam is to be obtained from"steam graph" etc. In this application, specific weight (γ) of 9Kgf/cm G steam is 0Kg/m. Saturated steam curve (by temperature) is shown on Fig. and Saturated steam curve (by pressure) is on Fig.7 for reference. Normally, flow rate of steam is described in weight unit, which is to be converted to volume unit (Qs) as follows: t/h = 0Kg/h Qs = 0 (Kg/h) /0Kg/m = 9 (m /h) Then, all these figures are to be put into the formula: QW = 9 0.0 0 = m /h Referring to Table 7 on p. 0, the suitable meter size is mm. For possible connection flange sizes, refer to"table" 7". Connection flanges Table 7 shows possible connection flange sizes against selected meter sizes. The table is applicable for flowmeters with Metallic materials, Rubber lining, ETFE lining. Only listed connection sizes in dimension tables are available for flowmeters with lining and Glass lining.
