Cooling fin (Model AM7□□□/FB) A cooling fin is to be provided between tube part and indicator hous- ing to release fluid heat in case fluid temperature is more than 150°C. Cooling fin is available for models AM72□□ (Bottom-Top side), AM73 □□ (Bottom side-Top side), AM76 □□ (Left- Right) and AM77□□ (Right-Left).
Jacket (Model AM7□□□/JS, Semi-jacket, AM7□□□/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 AM71□□ (Bottom-Top) and AM72□□ (Bottom-Top side). Only 150 lbs rating is available for full-jacketed flowmeters (AM□□□/JF).
Liquid damper (Model AM7□□□/DL) 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 AM73□□ (Bottom side-Top side), AM76□□ (Left- Right) and AM77□□ (Right-Left).
Gas damper (Model AM7□□□/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 con- sists of piston and cylinder. As it is not required to install liquid damp- er 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 chemi- cal compound) and gas containing rust, trash and oil may hinder the function of piston part. Consult factory for details. Available size is 20mm to 100mm (Not available for 15mm) and only for metallic mate- rial (Not for lined material).

Slurry (Model AM7□□□/SL) The structure of the float and float part allows solids to pass easily. Accordingly, this model is suitable for measuring liquids containing fibers, granules, etc. In addition to the standard stainless steel, PVC lining is available, which is suitable for plating drainage and other highly corrosive liquids. Guide Float rod Float
Sanitary (Model AM71□□/SR) This model is designed and manufactured for sanitary processes. It can be fitted onto process lines through IDF clamps (ISO standard). All wetted parts are buff polished (#320 to #400). It can be easily disassembled and assembled for cleaning. The electrolytic polish - ing is also available as an option.

Viscosity limit In case the Viscosity of fluid is more than 1mPa·s, confirm the suitability shown in the fiigure 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 com puter.

Viscosity curve Flow rate [L/h] Viscosity [mPa·s] c. Slurry application Consult factory if contaminations, sand, dirt and other solid particles are expected in fluid. AM7□□□/SL series slurry flowmeter is avail- able. 2. Gas application Generally, flowmeters with damper (Model AM71 □□/DU, AM72□□/DU, AM73□□/DU, AM73□□DL, AM76□□/DL, AM77□□/DL) are rec- ommended for gas application to prevent float vibration. Selection of meter size Maximum possible flow rate for each meter size is shown in dimension tables of AM71□□/DU, AM72□□/DU, AM73□□/DU, AM73□□/ DL, AM76□□/DL, and AM77□□/DL flowmeters. If actual fluid condition is different from such figures, a conversion calculation is to be performed by the following formula: QA : Converted /f_low rate in air 0°C, 1atm [m 3/h(nor)] : Density of gas to be measured [kg/m 3(nor)] p : Pressure of gas to be measured (MPa) t : Operating temperature (°C) Example Gas to be measured : Nitrogen (N2) Speci/f_ic weight ( ρ ) : 1.251kgf/m3(nor) Operating pressure ( p ) : 0.6MPa Operating temperature ( t ) : 20° C Flowmeter to be used : AM73/uni25A1/uni25A1/DU = 300×0.0169×22.86 ρ ρ SELECTION OF FLOWMETER 1. Liquid application a. Selection of meter size Maximum possible flow rate each meter size is shown in dimension tables from Page 15 to 22. These figures are based on water flow (Den- sity 1.0g/cm 3 and Viscosity 1.0MPa·s). If actual fluid condition is different from such figures, a conversion calculation is required as follow- ing formula: Qw : Water converted /f_low rate (m 3/h) Q : Flow rate of actual /f_luid (m 3/h) : Density of actual /f_luid (g/cm 3) Example Fluid: Alcohol Density: 0.8g/cm 3 Flow rate: 50m 3/h Flowmeter to be used: AM71/uni25A1/uni25A1 ρ ρ = 50×0.882 = 44.1(m 3/h) Referring to table 1 on Page 15, the required meter size is 100. For possible connection flange sizes, refer to Table 45. Referring to table 15 on Page 17, the suitable meter size is 25. For possible connection flange sizes, refer to Table 45.

Steam application Flowmeters with liquid damper (type AM73 □□/DL, AM76□□/DL, AM77□□/DL) are recommended for steam application to prevent float vibration. Also a cooling fin is normally needed because of high temperature. Selection of meter size Steam flow rate is to be converted into water flow rate by the following formula for size determination. Qw = Qs×0.03× Qw : Water converted /f_low rate (m3/h) Qs : Steam /f_low rate (m 3/h) : Density of steam (kg/m 3) ρ ρ Example Fluid Saturated : Steam Pressure : 0.9MPa Flow rate : 1t/h Flowmeter to be used : AM76□□/DL First, density of the steam is to be obtained from “Steam graph” etc. In this application, density(ρ ) of 0.9MPa steam is 5.1kg/ m3. Saturated steam curve (by temperature) is shown in the fiigure below and saturated steam curve (by pressure) is shown in the fiigure below for reference. Normally, flow rate of steam is described in weight unit, which is to be converted to volume unit (Qs) as follows: 1t/h = 1000 kg/h Qs = 1000 kg/h / 5.1 kg/m 3 = 196 m 3/h Then, all these figures are to be put into the formula: Qw = 196×0.03× 5.1 = 196×0.0677 = 13.3 (m 3/h) Referring to Table 21 on Page 18, the suitable meter size is 65. For possible connection flange sizes, refer to Table 45.

This flowmeter transmits the displacement caused by the magnet coupling. A surrounding magnetic field might affect its performance.
Avoid installation near magnetic fields. Magnetic materials including insulation covers may also affect its performance; do not bring them within 20 cm from the flowmeter.
When installing two or more flowmeters, place them at least the distances shown in the figures below apart from each other to avoid mutual interference. For maintenance, ensure a clearance of at least 20 cm between the indicator of one flowmeter and the body of other flowmeters.
