Jogler direct-reading liquid level / flow indicators are a simple, leak-proof way to observe liquid level in a vessel. Unique PTFE Teflon SuperSeals act as both the flange sealing face and sight tube seal so that only the Teflon and Borosilicate glass sight tube are wetted, pressure-bearing parts (Teflon lined models have only FEP as the wetted part).
