A flow monitor (65) for monitoring application of a matter through a first flow path (110) having a first outlet (130) and a second flow path (115) having a second outlet (135) is described. In order to provide a flow monitor which is less costly and complex with regard to existing flow monitors it is proposed to provide a first temperature sensing device (70) positioned adjacent the first outlet (130) and producing a first temperature signal, a second temperature sensing device (75) positioned adjacent the second outlet (135) and producing a second temperature signal and a signaling device (95), remote from the first outlet (130) and remote from the second outlet (135), the signaling device (95) is activated when the first temperature signal differs from the second temperature signal by a predetermined value. Further an agricultural implement with above mentioned flow monitor is described.
