Los equipos UOL son medidores de caudal de canal abierto sin contacto, con baja área ciega, alta sensibilidad y alta estabilidad. Consiste en una sonda ultrasónica y el anfitrión, principalmente utilizado para medir la conservación del agua de riego, plantas de aguas residuales, empresas e instituciones de la tasa de caudal de los vertidos de aguas residuales, las aguas residuales urbanas empresas química.
Característica:
Múltiples funciones, con cálculo, control, transmisión y otras funciones.
Coincide con varios tanques de presa. Presa triangular en ángulo recto, presa rectangular, ranura, canal de evacuación, ranura para canal de garganta.
Medición precisa: función automática de compensación de temperatura, sistema de filtrado automático, protección contra atascos.
Medición precisa en regiones más frías con sensor eléctrico de trazado de calor
Con control remoto IR, fácil de operar.
Gran pantalla, display LCD de cristal líquido de 14 bits de doble línea (con retroiluminación), caracteres de la interfaz hombre-máquina.
Con la comunicación serie RS485, el protocolo estándar MODBUS RTU, puede comunicarse con dispositivos Ethernet, PC, PLC y DCS.
Puede proporcionar hasta 6 relés, puede ajustar el límite superior y el límite inferior de alarma y control (caudal instantáneo y nivel de agua), puede ajustar alarmas de alto, bajo y fallo.
