Exd protection Tu r b i n e flowmeters Series TM Working principle One helicoidal rotor turns freely inside a cylindrical tube. The working liquid pushes the rotor blades, making them turn at a flow speed which is proportional to the flow rate. A pick-up coil mounted externally receives the propeller turns and generates an electrical signal which, once treated by the different electronic converters, provides: - Flow rate indication - Total or partial volume - Digital and analog outputs (mA, Hz and V) Applications ??

A straight pipe run without any disturbing element (elbows, valves, filters, etc) of 10 x DN before and 5 x DN after the turbine flowmeter is required. The upstream distance can be reduced to 5 x DN if a straightener is installed. In order to avoid that small pa rticles can damage the turbine propeller it is mandatory to inst all a filter before the flowmeter with a mesh size of 1 mm up to DN100 and 3 mm for bigger sizes. In those processes where air or gases, liquid evaporation, etc. might be present, an air/steam separator must be installed before the turbine flowmeter, in order to avoid measurement errors.

In order to do this, on the outlet of the flowmeter the pressure must be at least twice the pressu re drop of the flowmeter, plus 1.25 times the vapour pressure of the liquid. The wiring between the turbine flowmeter and the associated electronic converters must be made so that no mains or power supply cables are placed around th e devices, in order to avoid picking up interferences that might affect the reading. For an optimal signal transmission the following is recommended: - up to 30 m, 2-wire shielded cable - up to 100 m, installation of pulse amplifier model APTM44 - up to 3000 m, installation of Hz/mA converter model CP … CH420L Dimensions All dimensions in mm 4 Flow ranges DN Flow scales m 3/h water Max. intermittent m 3/h water pulses / litre approx. 15 0.3-3 4 730 20 0.6-6 8 500 25 0.9-13.6 16 220 40 1.9-30 40 60 50 5-50 60 20 65 9-90 115 10 80 15-150 180 5 100 28-280 340 3 125 45-450 560 1.5 150 65-650 820 0.8 ?

It is recommended that minimum fl ow rate is at least 10% of the flow scale in order to obtain the highest accuracy. The measurement errors can be corrected in the different associated electronic converters by means of the adjustment of the k factor (pulses / volume unit), obtaining a maximum accuracy. A change in viscosity can modify the k factor. The measurement error due to these changes in viscosity is approximately indicated in the curves on next page. In general, changes in density and viscosity affect the turbine flowmeters. The higher the dens ity and the viscosity are, the lower the initial flow rate required is so that the propeller starts turning, that is, the lower the be ginning of the scale is. In the same way, for lower values of density and viscosity, the beginning of the scale is higher. The TM turbine flowmeters are suitable for liquids with viscosities up to 100 mPa·s, although it is very important that liquid viscosity remains unchanged during operation in order to avoid measurement errors. 5 Flow rate (%) Variations of pressure drop due to the effect of density and viscosity Flow rate and pressure drop (?P) curves Flow rate 1000 ?P (mmH 2O) m3/h 100 10 1000 l/h 100 100 1000 10000 DN15 DN20 DN25 DN40 DN50 DN65 DN80 DN100 DN125 DN150 Effect of viscosity for liquids +1 Error (%) 0 0 50 100 0 50 100 -1 100 mPa·s 1 mPa·s 5 mPa·s 25 mPa·s 50 mPa·s ?P (mmH 2O) Value ?P (mH 2O) graph 1 ?

There are two types of protection available: Exi intrinsically safe or Exd ExProof. Exia protection This device is considered as “simple apparatus” according to EN 60079-11 standard clause 5.7, since it does not contain its own source of ignition. Pick-up coil technical data: - Li ? 700 mH - Ci ? 30 pF - Internal resistance > 1700 Ohm - Ui ? 3 V According to these data, the turbine flowmeter can be installed in hazardous area when an appropriate zener barrier (please consult) is installed between the hazardous and the safe area. The electronic converters, however, must always be installed in safe area. Exd protection These devices conform the 94/9/ CE directive (Devices and protection systems for use in potentially explosive atmospheres) as indicated in the CE certificate type LOM 14ATEX and its corresponding marking. The instrument belongs to group II, therefore it is intended for use in places where there is a risk of generation of an explosive atmosphere, except in mining. Being category 2GD it can be used in an environment where it is probable to generate an explosive atmosphere due to air and gases mixtures, vapours, mist and dust as well. Three different types of Ex d housings are available: - Model ADF30: blind housing with reduced dimensions - Model ADF60V: housing with window, can include the CIP … CIP II or CP ... CH420L converters - Model ADF60: same as ADF60V but blind housing Exd version technical data: - Ambient temperature: -20ºC ... +60ºC - Electrical wiring inside the Exd housing - On request ATEX packing glands for standard or shielded cable - Associated electronics, for models: - CIP ... CIP II: totalizer battery powered - CP … CH420: transmitter 2-wire system with flow rate indication, volume totalizer and 4-20 mA output.
