FUNCIONAMIENTO DEL CONJUNTO
A la puesta en marcha se encienden los tres leds de estados (verde, rojo y amarillo) delcontroladorBPS-3500/LD indicando que est realizando el Test de Inicio de comprobacindel buen funcionamiento del equipo.
Una vez acabado el Test de Inicio, y durante el funcionamiento del equipo, el led verdeparpadear siempre, indicando que el controlador funciona correctamente.
En situacin de nivel correcto, el rel Y1 tendr cerrado 6 - 7 e Y2 tendr cerrado 8 - 9.
En esa situacin, si el nivel baja del punto establecido por el extremo de la varilla de lasonda, se activa el led rojo (indicador de error), y 4 seg. despus desactiva el rel Y2abriendo 8 - 9 (situacin de error) y adems conmuta el rel Y1 (parada de seguridad)abriendo 6 - 7, para duplicar la seguridad, permaneciendo as hasta la restitucin delliquido a su nivel correcto.
Mientras el nivel es correcto, el equipo est programado para realizar rutinas de test deestado de la sonda automticamente cada 2 min. simulando dos condiciones de alarma:
1 Seguridad del controlador y 2 Seguridad de la sonda
Por tanto, la rutina de test consiste en comprobar peridica y automticamente elfuncionamiento del controladorBPS-3500/LD y de la sonda LDP-400, as como susconexiones, tanto internas como exteriores, mediante un la deteccin de depsitosconductores o humedad en la zona de test (ver figura) de la sonda.
El test tiene una duracin de 1 segundo durante el cual se cruza automticamente elsensor de test a masa y se enciende el led amarillo. Esta accin provoca que se activela alarma de situacin de error,encendiendo el led rojo durante 1 segundo,indicandoas que el sistema de vigilancia de la sonda de nivel ha funcionado bien, pero sin llegar a
accionarlos rels Y2 (de indicacin de error) ni Y1 (de parada de seguridad) quepararan la caldera. A continuacin, si el controlador est bien, al apagarse el led rojo(estado de alarma) desconectar la accin de test que la origino (led amarillo), indicandoas, que el controlador ha cerrado la rutina de test sin problemas.
En el supuesto que el sistema de seguridad detectara un fallo en la integridad delcontrolador, de forma que no cerrase el ciclo de test, ambos leds (amarillo y rojo) sequedaran encendidos y los rels de alarma y de seguridad se desconectaran 4 seg. mstarde, parando la caldera, permaneciendo en esa situacin indefinidamente hasta que seeliminase el origen del problema.
En el otro supuesto, que algn cable se hubiera desconectado o que la sonda estuvieramal, slo elled rojo permanecera encendido y los rels de alarma y de seguridad sedesconectaran 4 seg. ms tarde, parando la caldera, permaneciendo en esa situacinindefinidamente hasta que se eliminase el origen del problema.
Si, por el contrario, no se detecta error, pasado el tiempo de test,se apagan el ledamarillo y el led rojo volviendo al modo de medida normal durante otros 2 minutos.Pasado ese tiempo (2 min.) vuelve a realizar la rutina de test (1 + 1 seg.) de formasecuencial.
La funcin del sensor de test es para que si se depositasen residuos, incrustaciones ohumedad entre el sensor de nivel y el metal de la caldera, o el nivel alcanzase ese puntode test, se producira una seal de error. Esta error provocara la activacin del led rojo,y 4 seg. despus desactivara el rel Y2abriendo 8 - 9 (situacin de error) y adems
conmutara el rel Y1(parada de seguridad)
abriendo 6 - 7, para duplicar la seguridad,
permaneciendo as hasta la limpieza de los depsitos o que volviera a su nivel correcto.

Allgemein
Der Mewertgeber ist ein Fluidistor-Oszillator, dessen Schwingungsfrequenz direkt proportional derGeschwindigkeit des den Fluidistor durchstrmenden Gases ist.Das Verhltnis Frequenz/ Durchflugeschwindigkeit ist innerhalb eines groen Bereiches konstant.
Der Fluidistor ist parallel zu einem Unterteil geschaltet, der eine Drossel mit dem gleichenDurchflukoeffizienten wie der Fluidistor besitzt. Nur ein bestimmter Anteil des gesamten Durchflussesstrmt ber den Fluidistor. Nachdem jedoch das Verhltnis zwischen den beiden Durchflumengen konstantist, gilt die Oszillations- oder Schwingungsfrequenz des Fluidistors als Ma fr den Gesamtdurchflu durchdas Megert.
Das Bild oben rechts zeigt den Fluidistorteil. Der Teilstrom tritt von links in den Fluidistor ein und verlt ihndurch den rechten Anschlu.
Der Gasstrom whlt abwechselnd den einen oder anderen der beiden Kanle unmittelbar stromaufwrts desAuslaufanschlusses. Die Schwingungen zwischen diesen beiden Kanlen werden durch die hin- undhergehende Strmung in dem U-frmigen Kanal, der die beiden Steuerffnungen verbindet, bestimmt.
Die Oszillatorfrequenz, die der Wechselfrequenz entspricht, wird in diesem Verbindungskanal mit einemHeidrahtfhler gemessen.Der Fhler kann ohne Ausbau des Megerts aus der Leitung ausgewechseltwerden. Der Fhlerwechsel hat keinen Einflu auf die Eichung der Meeinrichtung.
In einem Signalwandler werden die Schwingungen in ein Impuls- oder Analogsignal verstrkt, das z.B. voneinem Zhler und einem Anzeigeinstrument empfangen werden kann.
Druckverlust/Durchflu
Das Diagramm gilt fr Gase mit einer Dichte von Luft beiNTP (0C und 1000 mbar). Der Druckverlust ist stetsproportional der Dichte des Gases.Bei z.B. 100% hherem Betriebsdruck liegt doppelterDruckverlust vor.

Kleinere als DN25 und grere als DN400 werden auf Wunsch
angeboten. Grere Messer als DN400 mssen vor Ort mit Hilfeeines Wirkdruckmessers geeicht werden.
EinbauanweisungDer Durchflumesser kann in waagerechter odersenkrechter Lage eingebaut werden. WennKondensat oder hnliches im Gas vorkommt,mu der Messer waagerecht eingebaut werden,mit dem Mekopf nach oben. Eine geradeEinlaufstrecke des Messers von 10x DN und eineAuslaufstrecke von 5x DN ist zu empfehlen.Im Rohrnetz vor dem Durchflumesser darf dieGasgeschwindigkeit nirgends dieSchallgeschwindigkeit berschreiten.berkritische Druckabflle mssen vermieden
werden. Auch pulsierende Strmungen.

MessgenauigkeitDie Dichte (oder eigentlich die Zhigkeit) desGases beeinflut bei niedrigenGeschwindigkeiten die Megenauigkeit. berdem Grenzwert Qt betrgt die Genauigkeit 1,5% des Messwertes. Unter Qt betrgt dieMessgenauigkeit 5% des Messwertes.
Beispiele:Bei einer Dichte von 1 kg/m3 ist Qt = 8% von QmaxDie aktuelle Dichte soll mit der Formel:
T
TPDD 00 **=
berechnet werden, wobei P = Druck (bar abs)T = Temperatur (K)D = Dichte (kg/m3)D0 = Dichte bei NTP (kg/m
3) ist.
