Sea V Holding Tank Level Gauge | KUS JMV00072

KUS Sea V Holding Tank Level Gauge | JMV00072 | CPGR-BS-240-33 | Black Face, 316 Stainless Bezel | 2" Mount | IP67 | Low–Full

The KUS JMV00072 is the Sea V holding tank level gauge in black face with 316 stainless steel bezel finish. Model CPGR-BS-240-33 mounts in a standard 2-inch gauge opening and reads tank level on a continuous Low-to-Full sweep using standard 240–33Ω tank level senders. Rated IP67 for waterproof and dustproof protection. Suitable for helm stations, flybridge, and enclosed or exposed panel installations. Compatible with 12V and 24V DC systems. Also sold under the Wema brand — KUS and Wema are sister brands under the same parent company.

Additional Information

Low–Full vs. Empty–Full — Face Label Difference:

The JMV00072 face is labeled Low–Full rather than Empty–Full. This is a face graphics difference, not a functional or sender compatibility difference — the gauge still uses the same 240–33Ω sender range and continuous sweep mechanism as other Sea V CPGR variants. For holding tank monitoring, Low–Full labeling is conventional — holding tanks are rarely run to completely empty, and the Low indication serves as the practical lower reference point for service planning. All three Sea V CPGR variants are compared below.

Sea V Gauge Family — Color, Bezel, and Face Label Options:

All Sea V CPGR holding tank gauge variants share the same 2" mounting cutout, 240–33Ω sender range, and continuous sweep mechanism. Differences are finish and face label only:

• CPGR-BS-240-33 (JMV00072) — Black face, 316 stainless steel bezel, Low–Full sweep — this product
• CPGR-WS-240-33 (JMV00004) — White face, stainless steel bezel, Empty–Full sweep — see the KUS Sea V White Face / Stainless Bezel (JMV00004)
• CPGR-BB-240-33 (JMV00039) — Black face, black plastic bezel, Empty–Full sweep — see the KUS Sea V Black Face / Black Plastic Bezel (JMV00039)

Select the variant that matches your panel color scheme and bezel preference. All three variants use the same sender, cutout, and mounting hardware.

316 Stainless Steel Bezel:

The JMV00072 uses a 316-grade stainless steel bezel — the marine-grade alloy with superior chloride and saltwater corrosion resistance compared to standard 304 stainless. The 316 stainless bezel paired with a black face is a popular combination for offshore, sportfish, and dark-panel helm installations where a blacked-out instrument aesthetic is preferred without sacrificing bezel durability.

KUS and Wema — Same Company, Two Brand Names:

KUS and Wema are sister brands operating under the same parent company. Products sold under the KUS brand and Wema brand in the same category are manufactured to the same specifications. If you encounter references to this gauge under either the KUS or Wema brand name, they refer to the same product family.

240–33Ω Sender Compatibility:

The JMV00072 is calibrated for the standard marine 240–33Ω sender resistance range. Verify your holding tank sender resistance specification before purchasing. Common compatible sender brands include Wema, KUS, Faria, and Rochester. If your vessel uses a different sender resistance standard (e.g., 0–180Ω), this gauge will not read accurately without a sender replacement or signal converter.

IP67 Protection:

IP67 means the gauge is fully dust-tight and rated for temporary water immersion to 1 meter for up to 30 minutes — appropriate for exposed helm stations, open flybridge panels, and cockpit instrument locations subject to spray and wash-down.

Installation Notes:

• Panel cutout: 2 in. (51 mm) diameter
• Sender wiring: verify sender resistance is 240–33Ω before connecting
• Grounding: use a clean, dedicated ground — poor grounds are the most common cause of erratic level gauge readings

Frequently Asked Questions

1. What is the difference between this gauge and the other Sea V variants?
The JMV00072 (CPGR-BS-240-33) has a black face with 316 stainless bezel and a Low–Full face label. The JMV00004 (CPGR-WS-240-33) has a white face with stainless bezel and an Empty–Full label. The JMV00039 (CPGR-BB-240-33) has a black face with black plastic bezel and an Empty–Full label. All three use the same 240–33Ω sender, 2" cutout, and continuous sweep mechanism — the differences are finish and face label only.

2. Is the Low–Full label the same as Empty–Full?
Functionally, yes — both are continuous sweep gauges using the same 240–33Ω sender range. The face label difference (Low vs. Empty) is a graphics choice. For holding tank applications, Low–Full labeling is conventional since holding tanks are rarely run completely dry in practice.

3. What sender resistance does this gauge require?
The JMV00072 requires a 240–33Ω sender. Verify your holding tank sender's resistance specification before purchasing — a mismatched sender will produce inaccurate readings.

4. What size hole does this gauge require?
A standard 2-inch (51 mm) panel cutout. Confirm the available cutout size on your dash panel before ordering.

5. Is this gauge compatible with a 24V system?
Yes — the Sea V CPGR gauge operates on both 12V and 24V DC electrical systems.
